A part of an ecosystem that can restrict the growth of a population is referred to as _carrying capacityimmigrationa limiting factora resource

In an ecosystem, a limiting factor is any environmental factor that can restrict the growth, abundance, or distribution of a population. This can include factors such as food availability, water supply, habitat space, and predation pressures.

• Carrying capacity: The maximum population size that an environment can sustain indefinitely.
• Immigration: The movement of individuals into a population from another area.
• A limiting factor: The correct term for a part of an ecosystem that restricts population growth.
• A resource: Any necessity of life, such as water, nutrients, light, food, or space.

Thus, the correct answer is "a limiting factor".

Supplemental Knowledge

Ecology studies the growth of populations within ecosystems. One key concept in ecology is known as "limiting factors", or any factor which limits population size; such elements could include food sources, shelter, climate and temperature constraints as well as non-living sources like resources like shelter and space. Limiting factors also exist within living populations but can impact them significantly too if not taken into consideration when managing population sizes within an ecosystem.
Other relevant terms:

• Carrying Capacity: This is the maximum number of individuals in a population that an environment can sustain over time without degrading.
• Immigration: The movement of individuals into a population from other areas.
• Resource: Any necessity of life, such as water, nutrients, light, food, or space.

Practical Insights

Consider your fish tank as an ecosystem: by continuously adding new fish without increasing tank size or filter capacity (resources), eventually its carrying capacity will reach maximum, potentially becoming polluted due to waste accumulation which limits further fish population expansion.
