|---|---|---|---|---|---|
| How do you define ecology? | study of the interactions between organisms and their environment
🗑
|
||||
| The living factors within an environment are called? | biotic -( animals, plants)
🗑
|
||||
| The nonliving factors within an environment are called? | abiotic - (water, rocks, light, temperature)
🗑
|
||||
| Explain what is an organism | a living thing
🗑
|
||||
| Explain the differences between a population and a community. | A population is a group of organisms of the same species that live in a given area. A community is all the different populations that live in a given area
🗑
|
||||
| Give an example of a population. | Deer population that live in Southwestern Phillips County
🗑
|
||||
| Give an example of a community. | Deer, rabbits, plants, grass, humans, coyotes, etc that live in Southwestern Phillips County Kansas
🗑
|
||||
| How do you define an ecosystem? | a community of organisms and their nonliving environment
🗑
|
||||
| A biosphere is what? | the part of Earth where life exists
🗑
|
||||
| An organism that gets it's energy from the sun. | producer
🗑
|
||||
| The process of getting energy from the sun. | photosynthesis
🗑
|
||||
| Organisms that eats other organisms. | herbivores, carnivores and omnivores
🗑
|
||||
| An organism that eats plants. | a herbivore. - Examples: grasshoppers, prairie dogs and bison
🗑
|
||||
| An organism that eats consumers. | carnivores.- Examples: coyotes, hawks, badgers and owls
🗑
|
||||
| An organism that eats both plants and animals. | Omnivore. Examples: mice, raccoons, monkeys, turtles, humans
🗑
|
||||
| What is a scavenger? | Omnivores that eat dead plants and animals. - Example: turkey vulture
🗑
|
||||
| What is a decomposer? | organisms that get energy by breaking down dead organisms. Examples: bacteria and fungi
🗑
|
||||
| Explain the differences between a food web and a food chain. | food chain shows how energy in food flows from one organism to another; a food web shows the feeding relationships between organisms in an ecosystem
🗑
|
||||
| Describe what an energy pyramid tells a person. | The pyramid represents energy. In a community there must be more plants than herbivores and more herbivores than carnivores.
🗑
|
||||
| Is there more energy on the top or bottom of an energy pyramid? | There is more energy at the bottom of an energy pyramid
🗑
|
||||
| Explain the differences between limiting factor and carrying capacity. | limiting factor is a resource so scarce that it limits the size of a population; carrying capacity is the largest population that an environment can support at any given time
🗑
|
||||
| The resource that causes a population to stop growing is called? | limiting factor
🗑
|
||||
| The largest population that an environment can support at a given time. | carrying capacity
🗑
|
||||
| Two or more individuals or populations that use the same resource with in a biosphere are called? | competition

🗑
|
||||
| A relationship between two organisms where one benefits and the other is harmed. | parasitism
🗑
|
||||
| When two species change or adapt at the same time to benefit both species. | coevolution
🗑
|
||||
| When one organism is not affected and the other benefits, this relationship is called. | commensalism
