Intensity on the Rate of Photosynthesis in an Aquatic Plant Introduction The input variable I will be investigating is light, as light is just one of the 4 factors required in the green-plant process of photosynthesis. Photosynthesis is the process by which green-plants use sunlight, carbon dioxide, water & chlorophyll to produce their own food source. This process is also affected by the temperature surrounding the plant (the species of plant we experimented with, pond weed, photosynthesised
of Carbon Dioxide emission from Elodea plant after being exposed to different temperatures. Elodea also known as Elodea canadensis is a genus of aquatic plants. They are also called waterweeds and is mainly used in aquarium vegetation. It plays a significant role in aquatic vegetation as it produces a significant amount of carbon dioxide under the perfect conditions. Elodea mainly grows in shallow water and can also be sometimes found in deep water. The plant for this experiment is kept in a water
The name of my species is Hydrilla. The scientific name of this species is Esthwaite Waterweed. The classification is Alismatales because all plants that fall there is either aquatic or tropical. Hydrilla has really impacted our world. The Hydrilla plant may be "good" to goldfish, for the reason that they play with it, yet it can ruin anybody's life. It was brought from another country, but it really impacted people's lives and the ecosystems. Although Hydrilla was originally from warmer parts
General Purpose: To inform Specific purpose: The audience will know that the Dead Sea is devoid of all plant and aquatic life, why the sea is so salty and the health benefits. Thesis or central idea: The Dead Sea has a unique environment Main Points: a. The Dead Sea is one of the saltiest bodies of water anywhere b. The Dead Sea is devoid of all plant and aquatic life c. The Dead Sea area has become a major center for health research and treatment Introduction: You know why they
general area. An community is a population located in a certain area living among different species. An ecosystem is a larger mass of a population, a community, and abiotic factors. Ecosystems can be aquatic or terrestrial. The earth's aquatic ecosystem makes up about 75% of the earth's surface. This aquatic environment is divided into marine and freshwater environments. The earth's earthly ecosystem is mainly made up of forests and deserts, which make up for 25% of the earth's surface. The role or function
Introduction Duckweeds are small aquatic plants that float on the surface on bodies of water. One plant has a leaf-like structure with a root under the plant. The diameter of a leaf is usually not more than 0.5 cm (Duckweed). The water in its habitat has to be slow-moving or still, no faster than 0.3 m/second. Therefore they grow in areas that are protected from wind and waves. The water has to be nutrient-rich and fresh or brackish. They can be found in many places in the world as they can live
Savanna Theory Versus Aquatic Ape Theory of Human Evolution The evolution of man is constantly in question. While we are reasonably sure that modern humans and primates are both related to the same common ancestor, there is constant debate over what initially caused the two species to split into early hominids and apes. According to some, our longest and most popular theory on the division of man and ape is profoundly wrong. However, those same individuals usually offer an equally controversial
Measuring the Heart Rate of Daphnia Daphnia is the name of a group of small, aquatic crustaceans commonly called 'water flies'. Because their exoskeletons are clear it is possible to watch daphnia hearts without cutting them open. This also allows the changes in daphnia heart rate to be studied quite easily. Hypothesis I predict that a daphnia should have a heartbeat of 190 to 200 per minute. However this would also be dependent of the room temperature as daphnias
information on this new species they had to murder nine other whales, one ‘accidentally.’ This finding was a great feat for science because it is important to learn as much as we can about a species before they become extinct. The rate in which large aquatic mammals are reaching extinction has been rising. So although there is much to be found and much that has been found about not only the new species of the baleen whale, but also the other two species that have risen to the surface, it was not done

Sea Lions: Nature's Playful Aquatic Land Mammals Introduction Sea lions may look like sea creatures, but they also behave like terrestrial animals. Unlike whales, mammals that spend their entire lives in water, sea lions inhabit both the water and land throughout their lives. This aquatic land animal prefers the water for food, fun, and safety; while preferring the land for socializing, territory, and procreation. Being mammals, they share many behaviors common to humans and other mammals
behaviour of woodlice in a wet or dry environment or a light or dark environment. I chose to investigate the behaviour of woodlice in a wet or dry environment. Woodlice belong to the biological class crustacea. Most of the animals in this class are aquatic, and though the terrestrial species can breathe with the aid of primitive ‘lungs’ they lack the features found in most other land-dwelling arthropods. They have no waterproof waxy cuticle on their exo-skeleton and are therefore more likely to
The Evolution of Ichthyosaurs- Large Aquatic Reptiles In the early 1800’s, a new discovery that left paleontologists in awe was the fossil finding of the immeasurable amount of species of reptiles, Ichthyosaurs. Greek for “fish lizards”, these fossils were found all over the world. Because these large aquatic reptiles migrated just as whales do today, paleontologists have had the amazing advantage of collecting fascinating bone fragments throughout the past 177 years. Ichthyosaurs swam the ocean
for a long period of time is whether the anatomy for locomotion on land was developed in water for swimming purposes, or if it was adapted after the creatures became terrestrial. Recent findings of fossils indicate that the transformations of the aquatic creatures happened underwater in order to help them survive in the changing world. When looking for answers, they had to examine forearm, hip, wrist, finger, and other bones, as well as the lungs or gills of the early tetrapod fossils. This information
between aquatic and on land ecosystems. It wasn’t until recently that riparian areas have been viewed as important places, rather than ‘sacrifice’ areas that could be given up for livestock and crops. They take up a small part of our earth, but they are vital to ecosystems and to the water they surround. The roles of riparian areas are rather simple, but they are extremely important to vegetation, wildlife, water, and us. Riparian areas are the “in between” places between on land and aquatic ecosystems
oxygen level. freshwater fishes such as trout and heterotrophs can be found. Towards the middle part of the stream/river, its width increases, and also its species diversity — many aquatic green plants and algae are found. Toward the mouth of the river/stream, the water
‘highly productive ecosystems’ support the coastal and intertidal areas they are found within (Hogarth et al., 2007). They are invaluable, able to withstand varying levels of salinity and extreme weather conditions, playing a key role in the coastal aquatic ecosystems biological health and overall diversity (Wetlands International, 2012). They aid in the purification of the water, ridding it of potentially poisonous pollutants and toxins such as foreign wastes and poisons (National Geographic, 2010)
its surrounding environment. The study of ecology in ponds is critical in understanding the necessities required to produce a healthy body of water for recreational use. Inadequate ecology results in a toxic environment that is not suitable for any aquatic organisms to inhabit.(McCarty, Thomas) There are a variety of physical characteristics that make every pond one of a kind. Some of the characteristics include size, shape, depth, volume, aspect, and location. (Pattillo, Allen. Intro Guide to Pond
Although nitrates do not have a direct effect on aquatic organisms, in excess they can create conditions, which make it difficult for aquatic creatures to survive. Algae and other aquatic plants use nitrates as a source of food so if they have an increased supply of nitrates, their growth rates will drastically increase. This can cause an array of problems for an ecosystem
that are out there and what functions the different benthic organisms have in our oceans. Benthos can be classified as either phytobenthos, or zoobenthos (Benthic, What is Benthos). Phytobenthos are primary producers such as algae (seaweed) and aquatic plants like seagrass. Zoobenthos, on the other hand, are consumers like benthic animals and protozoa. Sugars are able to leak out of phytobenthos tissues as they rapidly produce carbohydrate molecules, then it attracts zoobenthos that consume the sugars
