are communities of organisms and their abiotic environment.
are environmental factors that are associated with or results from the activities of living organisms which includes plants, animals, dead organisms, and the waste products of organisms.
are environmental factors that are not associated with the activities of living organisms which includes air, water, rocks, and temperature.
are living things that can carry out life processes independently.
are groups of organisms that are closely related can can mate to produce fertile offspring.
are groups of organisms of the same species that live in a specific geographical area and interbreed.
are groups of various species that live in the same habitat and interact with each other.
A place where an organism lives
A grouping system that divides organisms into 6 major categories based on different characteristics
Smallest unit of biological organization
Contains the cell's genetic material
Structures that surround cells to provide them with support
Single celled organisms that live in extreme environments
Single celled organisms that are common; found in soil and animal bodies
Organisms whose cells have a nuclei and cell walls, mostly live on land, and absorb food through their body; mushrooms
Mostly singled celled, but some multicellular organisms that live mostly in water; Amoeba, kelp
Multicellular organisms with cell walls that make their own food using the sun's energy
A system of tubes that carries water and food with this cell walls
Woody plants that produce seeds that are not enclosed in fruits; Pine trees
Flowering plants that produce seeds in fruit; Flowers, grass
Organisms that cannot make their own food and have no cell walls
Animals that have a backbone; Fish
Animals that lack a backbone; Insects
Warm blooded vertebrates that have fur and feed their young milk
Ecosystems need five basic components:
energy, mineral nutrients, water, oxygen, and living organisms.
is a change in the characteristics of a population from one generation to the next.
is the process by which individuals that have favorable variations and are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do.
is the process of becoming adapted to an environment. It is an anatomical, physiological, or behavioral change that improves a population's ability to survive.
is the process of two species evolving in response to long-term interactions with each other.
is the selective breeding of organisms, by humans, for specific desirable characteristics.
is the ability of an organism to tolerate a chemical or disease-causing agent.
