How do the biotic and abiotic limiting factors of an ecosystem determine its carrying capacity?

The carrying capacity of an ecosystem is the total number of organisms it can support. Biotic and abiotic limiting factors such as the amount of available space, food, water, and shelter determine how many organisms can live within an ecosystem. An ecosystem with a high availability of these limiting factors will be able to support more organisms and will have a greater carrying capacity.

good one: produce hormones that plants grow.

bad one: the problem with organic matter is that while plant nutrients are needed for crop growth, they can also stimulate excessive growth of the wrong plants – mainly, algae.
