What is deforestation?

Back

The clearing or thinning of forests by humans, which can lead to increased carbon dioxide levels in the atmosphere.

Front

How does deforestation contribute to global warming?

Back

By increasing carbon dioxide levels, which enhances the greenhouse effect.

Front

What is exponential growth?

Back

A growth pattern where the quantity increases at a constant rate over time, resulting in a rapid increase.

Front

What is logistic growth?

Back

A growth pattern that starts exponentially but slows as the population reaches carrying capacity.

Front

What is a trophic level?

Back

A level in a food chain or food web, representing the flow of energy and nutrients.

Front

What happens to energy as it moves up trophic levels?

Back

Only about 10% of the energy is transferred to the next level; the rest is lost as heat.

Front

What is the significance of the 10% rule in ecology?

Back

It explains that energy transfer between trophic levels is inefficient, limiting the number of levels in a food chain.

Front

What are renewable resources?

Back

Resources that can be replenished naturally over time, such as solar energy, wind energy, and biomass.

Front

What are non-renewable resources?

Back

Resources that cannot be replenished within a human timescale, such as fossil fuels and minerals.

Front

What is carrying capacity?

Back

The maximum population size that an environment can sustain indefinitely without degrading.
