Genetic biodiversity is having a number of different organisms living in an ecosystem.
Species biodiversity is having a large number of different animals in an ecosystem .
Ecosystem biodiversity is having a large number of different ecosystem types in a single biome.
Hot spots are ecosystems with a large capacity of organisms living in them. They are mostly found on and near the equator.
Biotic Factors are all living organisms in an ecosystem. Examples: grass, trees, moss, fish, dogs, cats, bears, humans etc.
All non-living things in an ecosystem. Example: rocks, water, snow, sand, mud etc.
Limiting factors are factors in an ecosystem that keep the population in check. If ecosystems didnt have limiting factors the population would grow to unsustainable numbers and the ecosystem would begin to run out of resources needed to keep the inhabitants alive.
This is pollution that comes from places and things we cannot control.
Pollutants that were living
Water Purification, Desalination, Aquifer
These pollutants reach the water the same way as organic matter but inorganic pollutants include fertilizer, detergents, and other excess chemicals.
