Answer:

b.) diffusion

Explanation:

Gas exchange is occur through the diffusion across the surface.

Diffusion:

It is a process in which gas exchange is occur through the concentration gradient. Gas molecules are moves from region of high concentration to the region of lower concentration.

Example:

In blood the concentration of oxygen is low and carbon dioxide is high while the air in lungs is high in oxygen concentration and low in carbon dioxide concentration. This concentration gradient leads to the exchange of gases in respiration. During respiration oxygen gas is intake while carbon dioxide is released.

Serggg [28]

The three examples of cycles of inorganic nutrients are Nitrogen, carbon and sulphur cycle.

Nitrogen is required to make amino acids and DNA in organisms. Carbon is the main component of glucose through which organism make energy, about 18 per-cent of the human body comprises carbon. Sulphur is an important constituent of some proteins, amino acids and enzyme cofactors.

Explanation:

The biogeochemical cycles like the nitrogen cycle are responsible for converting nitrogen into many chemical forms as nitrates, nitrites, ammonia. This process involves degrade decomposing animal and plant matter and naturally cleaning the environment also nitrites and nitrates become biofertilizers. The plants take nitrogen through their roots and in turn primary consumer in food chain ie. organisms consume the plant and eventually releases nitrogen as a waste material, dead and decaying body to the soil and cycle goes on.

In the carbon cycle the carbon is exchanged from the atmosphere to the organisms and then again to the environment. Plants perform photosynthesis by using carbon dioxide, primary consumer eats it and gets nutrition to perform cellular respiration, in turn, gets energy which gets dissipated and stored as biomass eventually in the course consumer die and replenish the soil with carbon. The Carbon emitted will keep cycling through air, water and soil.

The sulphur cycle involves the movement of sulphur between rocks, water and living beings and plants. Plants ( producers) absorb sulphur dissolved in water and animal consume these plants to replenish their sulphur requirement. And when organism die, sulphur enter the cycle again.

There will be a transfer of these inorganic nutrients to the trophic level in food chain.

Climax community- most stable community that takes hundreds of years to develop. The types of organisms change due to __?__.
Svetlanka [38]

Answer:

competition

Explanation:

An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition and distribution are determined by environmental factors such as soil type, position in the landscape, altitude, climate and water availability(Department of Agriculture).

A climax community refers to the last stage of ecological succession in which the community remains relatively unchanged unless it is destroyed by events such as fire or human interference.

Competition between species in the same habitat is an important biotic factor in discussing ecological succession and the emergence of climax communities. Competition leads to a drop in the diversity of species in a given ecosystem because the dominant species live on and reproduce while the other species die off.
