1. Ecosystemsthe community of the forest needs certain things so that it may live. the ecosystem, and all the parts in it, work together. all of the different animals have a different niche, and without, or too much of one organism may destroy the whole ecosystem. this happens in the subject of ecology. the habitat population stays exactly the same throughout the whole ecosystem.
3. Food ChainsFood chains show the different places that energy travels. A food chain consists of producers, and consumers. Herbivores, carnivores, and decomposers is the order in which the energy is transferred. Food chains are also inside of food webs.
5. Symbiosissymbiosis is the relationship between two different organism in an environment. Things that work together have certain parts in an environment. parasitism is when a parasite hurts one organism but benefits itself. The host is the organism that is getting hurt. Commensalism is when one organism is benefitted and the other one doesn't mind. Mutualism is when both organisms are benefitted.
7. Population Growthpopulation is the number of species in an ecosystem. Limiting factors are the factors that could easily endanger a species if they weren't present in an ecosystem. Endangered animals have the possibility of becoming extinct species. Extinct species are a species that died out completely. Unlike them, threatened species have a possibility of becoming endangered.

2. Changes in EcosystemsThe conservation of trash and waste can severely help an ecosystem. But if the ecosystem does get destroyed, then succession takes place to bring it back. There are two different types of succession. Primary and secondary. Primary gives birth to brand new ecosystems and secondary heals the broken ones.
4. Food WebsFood webs show the different places that energy travels. A food web consists of producers, Herbivores, carnivores, and decomposers is the order in which the energy is transferred. Food Webs also contain food chains.
6. BiomesA biome is an ecosystem made up of many different habitats. They all have different climates and the animals inside of it have varying niches, or jobs.

1. The zooplankton (consumers) eat the phytoplankton (producers).
2. The Herring (prey) are eaten by the mackeral (predator).
3. The shrimp (parasite) harms the sea urchin (host).
