Which statement below accurately describes the carrying capacity of any ecosystem? a. it is not affected by any abiotic or biotic resources. b. it does not affect the species of an ecosystem. c. it is completely dependent upon the food supply. d. it is affected by both abiotic and biotic resources
The correct answer is D. It is affected by both abiotic and biotic resources
In ecology, the carrying capacity of an ecosystem refers to the population of organisms and other factors an ecosystem can support without decaying or degradation. Due to this, the carrying capacity includes biotic or living resources (animals, plants, fungi, bacteria, etc.) but also abiotic or non-living resources (minerals, water, soil, etc.), this occurs because living organisms depend on abiotic sources to survive and preserve the natural balance. In the same way, exceeding the carrying capacity affects negatively both abiotic and abiotic resources. According to this, the statement that is accurate about carrying capacity is "It is affected by both abiotic and biotic resources".
it is affected by both biotic and
1. Soil (abiotic component) provides nutrition to milkweed (producer) which undergoes photosynthesis to produce energy which is taken in by primary consumers (caterpillar) and these are eaten by secondary consumers (mocking bird).
2. The increase temperature due to global warming has caused coral bleaching thus disturbing aquatic ecosystem.
The destruction of biological diversity by cutting trees is a concern for ecosystem.
Ecological relations are the interactions between organisms and with their surroundings or environment.
The organisms depend each other be it abiotic or biotic components which are required for survival and growth.
In the components given of a particular system:
soli is abiotic factor, it has minerals and nutrients like nitrates, phosphates and water etc absorbed from the atmosphere. This soil is fed by milk weed.
milk weed is the producer as it undergoes photosynthesis to form glucose or energy source.
When milkweed is eaten by caterpillar which becomes primary consumer in this chain.
The caterpillar is preyed by secondary consumer in this food chain by mocking bird and the energy keeps getting transferred.
The two examples causing impact on abiotic components of ecosystem due to growing population are:
1) The coral bleaching has disturbed the aquatic ecosystem. The greenhouse effect is the major cause of it and emission of carbon dioxide has increased the earth's temperature. This increase in temperature has caused coral bleaching
2) The cutting of trees on large scale has caused a severe downfall in biological diversity and erosion of natural resources which has severely impacted ecosystem.
a) The milkweed is the primary producer in the ecosystem. It manufactures food from the abiotic factors in the soil such as nitrates and water and those in the atmosphere such as carbon-dioxide and sunlight. The milk weed is then fed on by the caterpillar and a primary consumer. The caterpillar is then fed on the mocking bird (secondary consumer)
b) Increased human population growth and their activities have resulted in the emission of carbon dioxide and other greenhouse gases in the atmosphere. This has increased the global temperature. This increase of global temperature increase ocean temperatures causing coral bleaching.
Another example is depletion of water sources by human activities hence causing drought. Drought reduces the amount of vegetation growth due to scarcity of water in the soil (due to lowering of the water table) for plant growth.
A. Competition can limit or deplete resources
Biotic resources are resources or substances which are derived from the biosphere like living things and from forest and the materials derived from them. ... Examples of biotic resources are forests, animals, birds, fish, and marine organisms.

The correct answer is c) The distributions of both albatross species are limited by the same biotic factors but their distributions are limited by different abiotic factors
Both of the species are limited in their nesting sites by predators, which represent the limiting biotic factors. They need to nest on the cliffs to avoid predators' access to their calves and in that way, they can ensure reproductive success.
Temperature is the limiting abiotic factor. Grey Albatross need to spend the winter in areas where the temperatures are warmer, while the Black Albatross are able to survive the colder southern winters.
THE RIGHT ANS IS :
IT IS AFFECTED BY BOTH ABIOTIC AND BIOTIC RESOURCES.
