The species population size is limited by environmental factors like adequate food, shelter, water, and mates. The use of inventions such as the mechanical corn picker and crop rotation – a way of growing different crops in a sequence that enriches the soil and leads to higher yields – allowed humans to produce even more food. It is illustrated that in ecology, carrying capacity focuses on the quality of an ecosystem (pressures on it) and corresponding population numbers, and less on equilibrium of populations as in biology.

But some scientists worry that we may be well on our way to exceeding the Earth’s carrying capacity – or that we may have already done so. The hypothetical “Daisyworld” model is a model developed by scientists to study how organisms change their environment, and how ecosystems self-regulate. All of these have the same carrying capacity for plants. 3. The carrying capacity is different for each species in a habitat because of that species’ particular food, shelter, and social requirements. The proliferation of poisonous algae, which can poison our water supplies and which feeds on the same fertilizer we use to feed our crops, is another worrisome sign that we may be exceeding our carrying capacity, and may begin to cause problems for ourselves if our population continues to grow.
