Science Ecosystems Project
Transcript of Science Ecosystems Project
There are so many parts to an ecosystem. All of them have to be present for everybody to live. BUT, how
do they work together? Well... A bit more about our ecosystem... a little to big eh?
lets go a little smaller. In our ecosystem there are a great many different animals. This table will give you an idea of the position of each animal in a food chain. Our Food Pyramid sharks seaweed plankton coral Mutualism Bacteria Commensialism Killer Whales Tuna Sea Lamprey attaches itself to
other fish by suction and chews on the flesh and kills most of the fish it attaches to. Barnacles growing on a whale to increase their chance of getting food and the whale is not harmed. The Minky Fish Commensalism Parasitism The tinner fish The moon fish sand crawler Niches Piranahs Bio invasion Predation Angler fish Within species Competition Resource Partitioning Manta ray Between Ecosystems Species Distribution clown fish Mutualism tailor fish Within Ecosystem A tailor fish swims beside a shark and eats the shark's harmful parasites and in return the shark protects the tailor fish. Producers are organisms that produce their own source of food. They rely on the sun and naturally occurring sources to create their own food. They are always at the bottom of a food chain, because they do not eat anything. producers So, how cam you categorize these creatures? Biotic Abiotic Sharks
Sand Consumers Consumers are animals that rely on producers to survive. This is because they do not produce their own energy. Instead they eat the producers, or other consumers. Decomposers are organisms that eat the decaying remains of dead animals. They leave a trail of healthy nutrients for plants to grow well in. they are the clean up crew of the eco-system.
Their place in a food chain is hotly debated, as they eat everything, and are not eaten, however, they do not consume anything living. Decomposers Disturbances Natural Disturbances Food Chain Droughts are very dangerous in underwater and above water. The animals have to interact more than their natural capabilities. Some animals do not survive these droughts because of over consumption of other animals because of the small space Human Disturbances this is what it looks like the extinct
the endangered the threatened and the unthreatened See the skit at oilskit.weebly.com There are many invasive species in the ocean these species are not supposed to be in this ecosystem. Species like the kelp eater, it releases poison into the plant and kills it. This cannot affect humans. They have no place in the community, so can only cause harm. Bioinvasion Extinction is a term used to classify ad species that are no longer alive. for whatever reason they have died out in all corners of the world. they will never be able to come back. Extinction In our eco-system, the Moon fish dies out.
this is because its main food source, the snapper
vine, becomes the victim of a deadly fungi.
The Moon fish is unable to adapt and starves.
This happens across the ocean. Kelp Eater Competition Competition is one of the deciding factors in the
survival. In the wild, there is only so much food, if a certain species doesn't have enough to eat, they cannot get anymore. So there will always be a fight for prey if two species eat the same animals. This COMPETITION can kill of a species. Predation Predation is is when a carnivore, or
secondary consumer hunts and kills another animal for food. In this act they
become predators. Unthreatened Expiration The unthreatened animal is an animal that can is easily
thriving in their habitat and is not threatened by extinction Threatened Threatened animals are animals that are almost going extinct. Another word for threatened is endangered. Endangered Climax Community Sea Turtles
Hammerhead Shark Endangered means to be threatened with danger or with extinction. When endangered, the species may have a 50/50 chance of being extinct. A climax community is an ecosystem
that has equal balance and a steady
rate of growth in all animals. The first thing that happens is the evaporation from the ocean and the forest goes into the atmosphere. and then the tiny water droplets condensate and as they get heavier, they start to fall (precipitation).
And from there, the waters evaporate again. the water cycle Examples: The carbon cycle
carbon dioxide was always there.
1. the plants consume carbon from the air and use it as food.
2. herbivores eat the plants and they eat the carbon with it.
3. the carnivore eat the herbvivores along with carbon.
4. the carnivore dies and as it`s body decays, the carbon is released back to the atmosphere The Carbon Cycle How this affects our ecosystem is that sometimes the cycle can be
unpredictable where the water levels could decrease because of no rain. the other side of that is that there could be way too much water and the pressure at the bottom of the small gulf could rise and fish living there could be squished and plants not get enough sunlight and die. the water cycle also helps our ecosystem by cleaning the water through rain and other precipitation.
