The community of a pond is made up of many different what? | populations |
When organisms can adapt to their physical surroundings or to each other this is called: | evolution |
An organism that rejects a chemical because it has a gene that protects it from the chemical has developed this | resistance |
The process of two species changing genetically in response to long-term interactions with each other is called? | coevolution |
Individuals with a trait that is “naturally selected” must have this occur for evolution to occur in a population? | reproduction |
Most scientists classify organisms into how many kingdoms? | six |
Converts nitrogen in the air into a form plants can use | bacteria |
What is an algae that uses energy from the sun to make food? | seaweed, phytoplankton or giant kelp |
Cone bearing plants with seeds not enclosed in fruits | gymnosperms |
Land animals depend on angiosperms for this | food |
Air and temperature in an ecosystem are this type of factor in an ecosystem | abiotic factors |
Humans have inadvertently promoted the evolution of insects by trying to control pests with chemicals which has created this in the insects | resistance |
Members of the same species living in the same place at the same time | population |
Bacteria and fungi are important to the environment because they are critical in doing this? | breaking down dead organisms |
Roots, insects and leaves are this type of factor in an ecosystem | biotic |

The initial source of food in most land ecosystems | plants –specifically angiosperms |
Pine trees and other conifers are classified as this because they are woody plants, the seeds of which are not enclosed in fruits | gymnosperms |
The living and once living parts of an ecosystem, including all the plants and animals, are this type of factor in the ecosystem | biotic |

Raccoons in a forest in Wisconsin would be described as this level of organization | population |
The place where an organism lives and that has the resources the organism needs | habitat |
Darwin proposed that this is the mechanism for the change in the genetic characteristics of a population from one generation to the next, aka evoluation. | natural selection |
An inherited trait that increases an organism’s chance of survival and reproduction in a certain environment | adaptation |
