Question

In a biotic community, the most important factor for the survival of an animal is
(a)Day length
(b)Soil moisture
(c)Green food
(d)Predators

Answer 1

Hint: Animals that live by killing and eating other animals. They are also known as omnivorous animals. They are present less in number than their prey in the ecosystem. They occupy the top level in the pyramid of biomass in the terrestrial ecosystem.

Complete answer:
In the food chain, the ending apex belongs to predator species or killer, detritivores, or decomposer species. In living, ecosystem food chains are important as the survival of most species where predators or consumers are those organisms that are organisms that eat other organisms. All the organisms except the first organism plant others are consumers.

Additional Information:
-Biotic factors represent the living organisms in the ecosystem. It is divided into three groups: producers, consumers, and decomposers.
-Producers group contains green plants that carry out photosynthesis to produce food.
-Consumers are those who feed on plants and other organisms, this is further divided into herbivores, carnivores, and omnivores.
-Decomposers are bacteria and fungi that break down dead plants and animals into simple substances.
-An interaction between two populations of the organism in which one organism known as predator hunts, capture and kill another organism known as prey for food.
-The size of the prey is mainly smaller than the predators but the numbers of prey are always more than the predators.

So, the correct answer is, ‘predators.’

Note: -The ecosystem is formed by the interaction of abiotic or nonliving factors and biotic or living factors.
-Abiotic factors affect the lives and distribution of organisms. It includes physical factors such as pH level, temperature, light intensity, humidity, topography, microclimate, and the edaphic factor i.e physical and chemical composition of the soil.
