Biology - Ecology and the Environment

An organism that eats other organisms

An organism that can make its own food.

An organism that feeds on producers.

An organism that eats primary consumers

An organism that eats secondary consumers

An animal that hunts other animals for food

Animal hunted or caught for food

An animal that eats other animals

An animal that eats only plants

An animal that eats both plants and animals

An organism that breaks down wastes and dead organisms, helps to recycle nutrients.

A series of steps in which organisms transfer energy by eating and being eaten

A community of organisms where there are several interrelated food chains

Representation of the number of individual organisms in each trophic level of an ecosystem

A pyramid that illustrates the total mass of all the organisms in a trophic level.

A measure of the total dry mass of organisms within a particular region.

Each step in a food chain or food web

A square used to measure and estimate population number and changes between different areas

A breaking down or rotting.

Movement of carbon in different chemical forms from the environment to organisms and then back to the environment.

Anything that is burned

Conversion of energy stored in glucose molecules into energy the cells can use

Plants using the sun's energy to convert water and carbon dioxide into sugars

A material found in air, water, or soil that is harmful to humans or other organisms

An increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic changes)

Gases such as carbon dioxide, methane, nitrous oxide, water vapor, and ozone in the atmosphere which are involved in the greenhouse effect.

Process by which atmospheric gases trap heat close to Earth's surface and prevent it from escaping into space

Destruction or loss of forests

pollution of water by fertiliser leading to excessive growth of algae on the surface preventing light from reaching the underwater plants

Place where an organism lives

All organisms of a particular species found in an ecosystem at a certain time.

A self-supporting system of organisms interacting with each other and with their physical environment.

The populations of all species found in an ecosystem at a particular time.

A group of similar organisms that can breed and produce fertile offspring.

Removal of dissolved materials from soil by water moving downwards

the washing away of soil by the flow of water

any substance such as manure or a mixture of nitrates used to make soil more fertile

A chemical intended to kill insects and other organisms that damage crops.

Heat transferred from one object through space/atmosphere to another object

the living factors in an organism's environment

Non-living components of environment.

The use of certain organisms by humans to eliminate or control pests. e.g. ladybirds to eat aphids
