Heat and Energy in Ecosystems

Front

What is the primary source of energy for ecosystems on Earth?

Back

The Sun

Front

What happens to the energy in the ecosystem as it moves up the food chain?

Back

It decreases due to inefficiencies.

Front

Where does chemosynthesis typically occur?

Back

Hydrothermal vents.

Front

What is a key factor in choosing a location for building a house to minimize heat transfer?

Back

Amount of direct sunlight.

Front

What is the primary benefit of adding insulation layers to walls?

Back

Reduces heat transfer.

Front

Define 'Ecosystem'.

Back

A biological community of interacting organisms and their physical environment.

Front

What is 'Energy Transfer' in an ecosystem?

Back

The movement of energy through a food chain from one trophic level to another.

Front

Explain 'Trophic Levels'.

Back

The hierarchical levels in an ecosystem, comprising producers, primary consumers, secondary consumers, and so on.

Front

What is 'Photosynthesis'?

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

Define 'Chemosynthesis'.

Back

The process by which certain organisms create energy by converting inorganic compounds into organic matter, typically in the absence of sunlight.
