What is exponential growth? give an example
Rapid rate of growth, where living things could grow endlessly. Human population, for example
How humans relate to the carrying capacity of the earth.
What is ecological footprint?
Why is Biodiversity a sign of a healthy ecosystem?
If many different living things can thrive in a n ecosystem, then the abiotic factors are promoting genetic diversity, a safeguard against pests and diseases that can threaten a biological community.
