Pollution can be found in greater amounts at higher trophic levels compared to lower trophic levels by Biomagnification. It indicates the presence or increase in the concentration of toxic materials or pollutants in the tissues of living organisms in a trophic level of an eco system.

Answer:

Through the process of biomagnification. An example is what happens with mercury in marine species.

Explanation:

Mercury is a pollutant known as a problem for the environment and the oceans, which affects the marine fauna to varying degrees and therefore the health of human beings. Methylmercury is the most toxic form of mercury and accumulates in the tissues of organisms. It is capable of bioaccumulating up to about one million times along the marine trophic chain, from microorganisms to predatory fish and mammals. In view of the ability to accumulate in organisms through trophic levels, higher concentrations are expected to be found in predatory fish and marine mammals (higher trophic levels), through the process known as biomagnification.

Class 10 differences between mutation and variation

trasher [3.6K]

Answer:

Main Difference – Mutation vs Variation

Mutation and variation are two simultaneous events involved in the process of evolution. The main difference between mutation and variation is that mutation is an alteration in the nucleotide sequence of a gene whereas variation is any difference between individuals of a particular species. Mutations may arise due to environmental factors such as chemicals and UV. Germline mutations are inherited by the offspring. Somatic mutations occur in the ordinary body cells. Variation can occur due to mutations, genetic recombination, gene flow, genetic drift, random mating, random fertilization, and environmental factors. Variation may also cause evolution through natural selection.

Why do some plants have more stomata than others?

zysi [14]

Explanation: All surfaces of the leaf have some amount of stomata for regulating gas exchange for photosynthesis. However, the lower epidermis (the underside of the leaf) has more, because it is more often in the shade and so it is cooler, which means evaporation won't take place as much
