What are food shortages and what causes them?

Back

Food shortages occur when the demand for food exceeds the supply. Causes include misuse of land resources, overpopulation, and environmental factors.

Front

Describe the flow of energy and movement of chemical compounds in an ecosystem.

Back

Energy flows from one organism to another in a food chain, while chemical compounds are recycled within the ecosystem.

Front

Why is biodiversity important for ecosystems?

Back

Biodiversity is crucial because all species depend on each other for survival; the extinction of one species can lead to the extinction of others that rely on it.

Front

What are renewable resources?

Back

Renewable resources are natural resources that can be replenished naturally over short periods of time, such as solar energy, wind energy, and biomass.

Front

What type of habitat supports the most sustainable ecosystem?

Back

A habitat with the greatest variety of living things supports the most sustainable ecosystem due to the interdependence of species.

Front

Define nonrenewable resources.

Back

Nonrenewable resources are natural resources that cannot be replenished within a human timescale, such as fossil fuels and minerals.

Front

What is environmental science?

Back

Environmental science is the study of the interactions between the physical, chemical, and biological components of the environment and the effects of human activity.

Front

Explain the concept of an ecosystem.

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic and abiotic factors.

Front

What role do producers play in an ecosystem?

Back

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

Front

What is the significance of ecological balance?

Back

Ecological balance refers to the equilibrium between living organisms and their environment, which is essential for maintaining biodiversity and ecosystem health.
