Why is variation an important part of a healthy ecosystem?

Variation within species affects how organisms interact with each other and their surrounding environment. For example, the size of a fish’s mouth, known as its gape, varies and determines the size of prey it can eat. Much of the time, traits like fish gape are adaptive; they help organisms live in a changing world.

Why is it important for an ecosystem to be healthy?

Healthy terrestrial ecosystems are vital for human welfare and survival, as they provide us with essential products and benefits. Over 90% of our food comes from terrestrial ecosystems, which also provide energy, building materials, clothes, medicines, fresh and clean water, and clean air.

How does variation within a species contribute to the health of an ecosystem?

How does variation within a species contribute to the health of the species? … The more variation the healthier the species as a whole. If environment changes then there is a chance that a gene will become advantageous and the species may survive.

What is the most important part of an ecosystem?

Soil Composition

Soil is one of the most important elements of an ecosystem, and it contains both biotic and abiotic factors. The composition of abiotic factors is particularly important as it can impact the biotic factors, such as what kinds of plants can grow in an ecosystem.

Why is variation important in species?

Having variation within a species means that if the environment changes there may be individuals within the species more able to withstand the change and survive. … it produces variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage.

Why is variation important for a species with example?

For example, a population with many different alleles at a single chromosome locus has a high amount of genetic variation. Genetic variation is essential for natural selection because natural selection can only increase or decrease frequency of alleles that already exist in the population.

How is variation important?

It helps in better survival of an organism. Accumulation of a particular variation over time leads to speciation. Variation results in genetic drift where same species are distanced. The useful variations are passed on to the next generation which is necessary for adaptation of an organism.

What are the most important factors in a healthy ecosystem?

An ecosystem must contain producers, consumers, decomposers, and dead and inorganic matter. All ecosystems need energy from an external source – this is usually the sun.

What is the most important part of an ecosystem Why?

Soil is a critical part of an ecosystem. It provides important nutrients for the plants in an ecosystem. It helps anchor the plants to keep them in place. Soil absorbs and holds water for plants and animals to use and provides a home for lots of living organisms.

What are the important parts of the ecosystem?

The major parts of an ecosystem are: water, water temperature, plants, animals, air, light and soil. They all work together. If there isn’t enough light or water or if the soil doesn’t have the right nutrients, the plants will die. If the plants die, animals that depend on them will die.

Why is it important for an ecosystem to be sustainable and balanced?

Favorable ecosystem ensures that each organism thrive and multiply as expected. They get enough food to keep them alive. Ecological balance is also important because it leads to the continuous existence of the organisms. It ensures that no particular species is exploited or overused.

What constitutes a healthy ecosystem?

A healthy ecosystem will have the right conditions for a wide range of organisms to survive and thrive. A healthy ecosystem will also have little pollution.
