All organisms in an ecosystem are interrelated by the abiotic and biotic resources they use in the course of their lives.
Nikolay [14]

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.

Explanation:

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.

The correct answer is C. Genetic analysis

Explanation:

In biology, two organisms have a phylogenetic relationship if they share a common ancestor and therefore have genetic similarities although in most cases there are also similarities in morphology, physiology, etc. However, two organisms might have similarities in morphology and physiology without genetic similarities. Due to this, if you need to determine whether two species are related or not the best method is a genetic analysis as only those organisms that share a common ancestor (phylogenetic relationship) are genetically similar.
