Ecosystem Examples:
Why We Chose This TopicWe chose this topic because we like to know about how nature works, how the animals interact, how they compete for food, what their habitats are, etc. It also help us understand the interconnections that people don't see at first glance. Normally people, unless you work with animals, don't understand that animals have niches, which( are roles. If you learn more about the topic then you get to know the wonders that Earth has to offer. You can find ecosystems anywhere, like in the forest. You can see how biomagnification works, which is when toxins get more concentrated as you go up the energy pyramid. You can understand how animals compete for food in the environment. What the different type of organisms are in the ecosystem. Which types of organisms they eat, which is why food webs and chains are made for. We chose it because you get to see the world through the eyes of the organisms that live on this planet as well.

What Is An Ecosystem?An ecosystem is a community of interacting organisms and their physical environment. The community can consist of plants, animals and smaller organisms that live, feed, reproduce and interact in the same area or environment. The main page shows an example of an ecosystem in a valley.

Different RelationshipsSymbiosis= interaction between two organisms.
Mutualism= Both organisms benefit. Commensalism= One organism benefits, the other is not affected. Parasitism= One organism benefits(parasite), the other is harmed(host). Competition= When two or more organisms fight for food, shelter and other resources they may need. Predator/Prey= When one organism eats the other organism. The one eaten is the prey, the one who eats it is the predator. |
Populations, Habitats and NichesAn ecosystem consists of different habitats and population of species. Each organism in a ecosystem has a specific niche that it has to either get food, find shelter, or protect itself.
Example: Finches and the tree. Each different kind of finch has a different place to either live or eat from. Each Finch has a different beak so there is no competition.

Energy Pyramids?An Energy Pyramid is a graphical model of energy flow in a community. Each step you move up the energy pyramid results in 10% of that organisms energy to be transferred to the next organism.

Food Webs and Food ChainsFood webs are the main handful of the organisms in an ecosystem. Food chains are a small part of the food web, and therefor the ecosystem. Food webs are more accurate in showing how the organisms interact with each other, and what each organism eats throughout it's whole ecosystem.

Types of Organisms
Herbivore= Eats plants
Omnivore= Eats plants and meat Carnivore= Eats meat Decomposer= An organism that decomposes organic material. Producers= Usually does photosynthesis to make its own food. Consumers= Eats other organisms to gain energy. Autotroph= Makes it own food for energy. Heterotroph= Eats other organisms to gain energy. |
