A Correct answer
Explanation

The ecological footprint is a measure of the amount of land and water required to produce the resources that a person or population consumes, as well as the amount of land and water required to absorb the waste that they produce. It is a measure of the impact that a person or population has on the environment.

Multiple choice

What is the term used to describe the amount of habitat that is available for a species to occupy?

  1. Habitat availability

  2. Habitat suitability

  3. Habitat quality

  4. Habitat fragmentation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Habitat availability is the amount of habitat that is available for a species to occupy, while habitat suitability is the degree to which a habitat is able to support a species, habitat quality is the overall condition of a habitat, and habitat fragmentation is the breaking up of a habitat into smaller and smaller patches.

Multiple choice

What is the term used to describe the variety of life on Earth, including the diversity of species, ecosystems, and genes?

  1. Biodiversity

  2. Biosphere

  3. Ecology

  4. Conservation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Biodiversity encompasses the entire spectrum of life on Earth, from the smallest microorganisms to the largest whales, and includes the genetic diversity within species, the variety of species within ecosystems, and the range of ecosystems across the planet.
