The meaning of Ecology is the connection that exists between living organisms and their environment. From the largest animal on Earth to the smallest, they all share our world with us. The ecosystem is connected by the flow of matter and energy and as organisms eat and dispose of matter it supplies them to sustain life. Across the planet various densities of uneven configurations accumulate minerals and nutrients.
For example “Energy necessary for all life processes reaches the earth in the form of sunlight. By photosynthesis green plants convert the light energy into chemical energy, and carbon dioxide and water are transformed into sugar and stored in the plant.” Para 3 Columbia Encyclopedia:

An animal that eats plants acquires some of the stored energy by consuming the plant; Herbivorous are then used for food by meat eaters and then they pass on the energy to them.
Ecosystems can be as small as a tide pool or a rotting log or as large as a body of water, forest or desert. Each system can consist of a community of plants and animals and this community is sustained by raw materials, chemical elements and water. Each community is surrounded by soil, water, climate and other conditions of the environment. An example of an ecosystem is a pond it supports a community of fish, frogs, insects and plants. Basic food is small organisms and plankton for the fish to consume. If the ecosystem does not maintain a balance it can weaken and the species will suffer. The systems are affected by fire, disease and severe climate changes not including predators and man such as building, pollution and mining.

Organisms just like us are aware of their environment. Animals can communicate by making sounds and body movement and leaving their scent. Plants can communicate through chemicals and color. Some plants use brighter colors to attract insects or other animals
Natural ecosystems function within the limits of their resources and are self sustaining. Over long period of times organisms can change their form and function this may cause them to no longer bear a resemblance to their original form.

Just one look outside and you will see all kinds of ecosystems. For example the oak tree is a ecosystem to all kinds of amazing creatures in the world. It is home to birds and bugs that live in it’s bark and its branches, and to the squirrels who make their nests in the trunks. It also provides food for other animals to. When an acorn falls off the branch deer and mice eat them too fatten up for the winter. The squirrel keeps them in it’s mouth. Another ecosystem is the ocean. One big part of that ecosystem is the coral reef. It is home to many plants and animals. For example sea plants move back and forth in the current, and fish and other sea animals come to hide in it just incase an animal harms or hurts it. Cool fact is that one quarter of all the fish in the sea live in that ecosystem. The coral reef also attracts other animals like birds, whales, turtles and seals. There are many different kinds of ecosystems small or big they are still a really big part of
Ecosystems are a system involving the interactions between a community of living organisms in a particular area and its nonliving environment. In the tropical forest there are many living and nonliving organisms that interactive for the daily growth and life in the forest. Tropical forest’s cover about seven percent’s of the earth and contains approximately fifty percent of the worlds’ species. Tropical rain forest is and interesting ecosystem, it contains different and a wide variety of species. All the species interact with one another to help sustain way of life.
The different types of components of an ecosystem are connected. it is very important to know, because a change in the amount of abiotic resources available or a change in the size of anyone in a certain population of organisms can have impact on the size of the other populations found in that ecosystem. Also the interactions that take place between the organisms that are found in an ecosystem can change the characteristics of some populations. One example that characteristics can be influenced by population interactions include the proportion of individuals within a population to have a specific traits or the average height or weight of the members of that population. One type of interaction that can result in a change in the characteristics of a population is a predation. It often has strong influence on the characteristics of a prey population. biologist study how the characteristics of a specific prey population change in the response to a specific type of predation and to understand how different types of interactions can result in a change in the characteristics of a population.
Ecosystem instability is a problem that we can no longer put off to the side. We are being confronted with this problem and we need to find ways to resolve the present situations. The forms of confrontation are through foriegn invaders and lack of apex predators (to name a few). We must realize that through research as well as changes in lifestyle we can save our planet. These changes must occur individually for them to be a true success.
In many parts of the world, ecosystems’ temperatures begin to rise and fall to extreme levels making it very difficult for animals and plants to adapt in time to survive. Climate has never been stable here on Earth. Climate is an important environmental influence on ecosystems. Climate changes the impacts of climate change, and affects ecosystems in a variety of ways. For instance, warming could force species to migrate to higher latitudes or higher elevations where temperatures are more conducive to their survival. Similarly, as sea level rises, saltwater intrusion into a freshwater sys...
People have been relying for their daily needs and well-being on nature. The natural ecosystem provides varieties of goods and services to us, for instance, fresh water, fisheries, timber, water purification etc. The benefits that people directly get from the natural systems are called ecosystem services (ES).
According to World WildLife Fund, many ecosystems around the world are being destroyed, eliminating many plant and animal species that inhabit them (“Pollution”). 2. And acid rain, which is created when water in the atmosphere mixes with chemicals, ravage through rain forests and can even kill fish. 3.
Scientists have begun to say that we have to do more to protect our ecosystem, because our very existence is depending upon it. When the ecosystem is not functioning properly the continuation of plant, animal and human life ecosystems would be impossible. Life cycles can not function without ecosystems. The ecosystem provides us with clean air, water, habitats for fish and other services. They also aid in the mod...
Green plants convert the radiant energy emitted by the Sun into useful chemical energy, such as the oxygen that we breathe. The energy transferred between any surroundings and any system can be in the form of various types of work, chemical, mechanical, radiant, electrical, or heat. The second law of thermodynamics is expressed as a cycle in which “all processes occur spontaneously in the direction that increases the entropy of the universe (system plus surrounding).” Entropy, the number of ways the components of a system can be rearranged without changing the system, plays a major role in the second law of thermodynamics.
The degradation of ecosystems and loss of biodiversity is increasing at an alarming rate every year. Humans are certainly not the only reason for this, but they are the main contributors. The well-being of ecosystems affects our everyday lives - consumption and consumerism depend on natural resources. Everything humans use is derived from them, in seemingly indirect and direct ways. Yet despite the fact that humans are destroying the environment, many continue to and neglect to take important measures to protect it.
Humans have many effects on the ecosystem that lower population and communities of other organisms. Although society cannot prevent all actions other people do towards the ecosystem, people can prevent a few in their day to day lives. The ecosystem is very important to human life, as it gives the atmosphere oxygen to breath. Over many years of careful examination, scientists have noticed huge changes in the ecosystem due to human actions, concluding with damaging results. Therefore human actions have many effects on the ecosystem.
The branch of science that deals with how living things, including humans, are related to their surroundings is called ecology . The Earth supports some 5 million species of plants, animals, and microorganisms. These interact and influence their surroundings, forming a vast network of interrelated environmental systems called ecosystems. The arctic tundra is an ecosystem and so is a Brazilian rain forest. The islands of Hawaii are a relatively isolated ecosystem. If left undisturbed, natural environmental systems tend to achieve balance or stability among the various species of plants and animals. Complex ecosystems are able to compensate for changes caused by weather or intrusions from migrating animals and are therefore usually said to be more stable than simple ecosystems. A field of corn has only one dominant species, the corn plant, and is a very simple ecosystem. It is easily destroyed by drought, insects, disease, or overuse. A forest may remain relatively unchanged by weather that would destroy a nearby field of corn, because the forest is characterized by greater diversity of plants and animals. Its complexity gives it stability.
