Science Test 4 biology

Front

Ecology

Back

The study of the relationships and interactions between living things and their physical environment.

Front

Ecosystem

Back

Ecosystem

A system of organisms interacting with each other and their environment.

Front

Organism

Back

Organism

A single living thing.

Front

Population

Back

Population

A group of the same type of organism living in a particular location.

Front

Community

Back

Community

Populations of different organisms that live in the same place.

Front

Describe photosynthesis as a process used by plants to make their own food

Back

Plants trap light with their leaves. They use the energy of the sun to change water and carbon dioxide into a sugar called glucose.

Front

Describe cellular respiration as a process to make energy in living things.

Back

Plants use cellular respiration and photosynthesis to keep making food for themselves like a cycle. Cellular respiration is what your body does to make energy. Inside your body, oxygen and food get mixed together in your cells. That gives you energy. So when your body makes energy from mixing food and oxygen, it also makes waste which is made out of carbon dioxide and water.

Front

Explain that organisms can hold multiple trophic levels in a food web

Back

Organisms can hold multiple trophic levels in a food web because many organisms don't fit into a single trophic level, because many species have various diets.

Front

Describe how the living and non-living factors interact and affect each other within an ecosystem.

Back

Biotic organisms, like plants, rely on abiotic factors such as sunlight, water, and soil for survival and energy. Also abiotic factors like temperature and climate can affect population of organisms.

Front

Define classification and taxonomy.

Back

Classification are items put into groups or categories based on characteristics.

Taxonomy is the science of naming, describing, and classifying organisms, including the rules involved in grouping them based on evolutionary relationships.
