Question

1. explain what a limiting factor is, and provide an example.
2. explain the term carrying capacity.
3. how do limited abiotic resources impact the overall biotic organisms in an ecosystem?

Explanation:

1. A limiting factor is a resource or environmental condition that restricts the growth, distribution, or abundance of an organism or a population within an ecosystem. For example, water availability can be a limiting factor for plants in a desert ecosystem. If there is not enough water, plant growth and survival are affected, which in turn impacts herbivores that rely on those plants, and the predators that eat the herbivores.
2. Carrying capacity is the maximum number of individuals of a particular species that a given environment can support over a sustained period of time. It is determined by factors such as food availability, water supply, habitat space, and other resources. Once the population reaches the carrying - capacity, growth rates slow down and may stabilize.
3. Limited abiotic resources such as sunlight, water, and minerals can have a significant impact on biotic organisms in an ecosystem. For instance, if there is a limited supply of water in an ecosystem, plants may wilt and die. This affects herbivores that feed on the plants, reducing their numbers. Consequently, predators that rely on the herbivores will also be affected as their food source diminishes.

Answer:

1. A limiting factor is a resource or environmental condition that restricts organism or population in an ecosystem. Example: water availability for desert plants.
2. Carrying capacity is the max number of a species an environment can support long - term, determined by resources.
3. Limited abiotic resources like water can harm plants, which then affects herbivores and predators in an ecosystem.
