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.

This describes how many protons reside in the nucleus and identifies the element.
denpristay [2]

Answer: D. Atomic Number

Explanation:

Atomic number of an element is the number of protons in the nucleus of an atom the element. An atom has three fundamental particles: protons, electrons and neutrons. Protons and neutrons are found in the nucleus of an atom while electrons are found outside the nucleus. The atomic number of an element determines the properties of the element. No two atoms of different elements have the same atomic number, but two or more atoms of the same element can have the same atomic number but different atomic masses. When atoms of the same element have the same atomic number but different atomic masses, they are said to be isotopes.
