Chapter 3 and 4- ECOLOGY EXAM

Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, encompassing all living organisms and their interactions with the environment, including land, water, and the atmosphere.

Front

What is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from clouds and reaches the ground, including rain, sleet, hail, and snow.

Front

Where does energy in food webs/chains originate?

Back

Energy in food webs and chains primarily comes from the Sun, which is harnessed by plants through photosynthesis.

Front

What happens to the grass population if grasshoppers are removed from the food chain?

Back

If grasshoppers are removed from the food chain, the grass population would likely increase because they would lose a predator.

Front

What type of cycle are the nitrogen, carbon, and water cycles classified as?

Back

The nitrogen, carbon, and water cycles are classified as biogeochemical cycles, which describe the movement of elements and compounds through living organisms and the environment.

Front

Define an ecosystem.

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic (living) and abiotic (non-living) components.

Front

What is a biome?

Back

A biome is a large geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions, such as deserts, forests, and grasslands.

Front

Explain the term 'food chain'.

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another, starting from primary producers to various levels of consumers.

Front

What is the role of producers in an ecosystem?

Back

Producers, primarily plants, convert solar energy into chemical energy through photosynthesis, forming the base of the food chain.

Front

Define 'community' in ecological terms.

Back

A community is a group of different species that live together in a specific area and interact with each other.
