Unit 7 Unpacking
Organisms get energy from oxidizing their food, releasing some of it as thermal energy. Organisms, in all environments, with similar needs compete with one another for limited resources such food, space, and water. Habitats are made up of biotic and abiotic factors and can change or even disapear.
Oxidation- The combination of a substance with oxygen.
Thermal Energy- The part of the total potential energy and kinetic energy of an object or sample of matter that results in the system temperature.
Limited Sources- Sources confined within limits.
Habitat- The natural home or environment of an animal or plant.
Species- A group of organisms consisting of similar individuals capable of exchanging genes.
Niche- The role an animal or plant plays in its habitat
Biotic Factors- Any living component in an ecosystem
Abiotic Factors- Any nonliving component in an ecosystem
Biotic & Abiotic Factors
Protecting Ocean Ecosystems
In my opinion, this unit is relevant to my everyday life because ecosystems are everywhere around us. Each ecosystem is unique too, we aren't limited to exploring one region.
1.How does population effect an ecosystem?
2. How do producers contribute to an ecosystem?
3.How do predators contribute to an ecosystem?
4.Explain how habitats change.
5.Explain how oxidation is beneficial to an organism.
6.Having limited resources causes increased competition among species. Give some examples of negative impacts this can have on an ecosystem.
7.Give examples of an abiotic factor. How does it effect an ecosystem?
8.Give examples of a biotic factor. How does it effect an ecosystem?
9.Compare "habitat" and "ecosystem".
10.Contrast "Symbiotic" and "Parasitic" relationships.
