State true or false.
The number of species that may live in an ecosystem is determined by the resources available as well as abiotic variables such as light and water availability, temperature range, and soil type.
- Every organism needs appropriate resources to live a normal life.
- Organisms also have to compete with each other for limited resources.
- So the number of species may live in an ecosystem is determined by the resources available in the ecosystem whether those are biotic or abiotic.
