Ecology Test
review for test
| What is an ecosystem? | consists of all the organisms living in that area, as well as the non-living parts of that environment |
| What are abiotic factors? | non-living things in an ecosystem |
| What are biotic factors? | living things in an ecosystem |
| What are herbivores? | a type of consumer that eats only plants |
| What are carnivores? | a type of consumer that eats only animals |
| What are omnivores? | a type of consumer that eats both plants and animals |
| What is the role of decomposers? | they break down dead plants and animals and then turn them back into soil |
| How does the transfer of energy work in a food chain? | an arrow points from the organism being eaten to the organism doing the eating |
| What are species? | an individual organism; do not breed with other individuals from other groups |
| What is a population? | a group of species that live in a specific geographic area at a given time |
| What is a community? | all populations living in an area |
| What is a biome? | a set of ecosystems in a geographic area |
| Explain competition in an ecosystem. | this is the attempt of organisms to obtain a resource that is available in a limited supply |
| What is a niche? | the role of the species in an ecosystem including where it lives and feeds |
| What is an adaptation? | characteristics that help an organism survive |
| how is competition reduced? | organisms have different or multiple ways of obtaining nutrients |
| What biome do we live in? | temperate forest |
| What is the water cycle? | demonstrates how water moves through the atmosphere and returns to the earths surface |
| what would happen if a drought reduced number of plants in a forest area? | drought-->producers die-->less food for primary consumers--> possible starvation and dying out |
| What are the 5 biomes? | ocean, ocean ( wetlands), temperate forests, desert, grasslands |
| What is the nitrogen cycle? | the process of nitrogen being fixed, used by plants and animals, and later returned to the atmosphere |
| What is nitrogen fixation? | changing nitrogen from air into more usable, compound, form |
| What is the role of decomposers in the nitrogen cycle? | bacteria whose function is to fix nitrogen, converting it, so plants can use it |
| What is the carbon cycle? | the movement of carbon, in its many forms, between the biosphere, atmosphere, oceans, and geosphere |
| mutualism | A relationship between two organisms where both are helped |
| commensalism | A relationship between two organisms where one is helped, and the other didn’t help or harm |
| parasitism | A relationship between two organisms where one is helped and the other harmed |
| ocean | water- colder at bottom tropical parts |
| temperate forest | no dry season- this is where we live |
| ocean wetlands | cool summers, warm winters- increased precipitation |
| desert | extreme temperatures and little rainfall; deserts can be hot or cold, think cactus, |
| grassland | large range temperatures from below freezing to 100-often connects forests to deserts |
