What are the 3 different levels of biodiversity?

Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms. It occurs within a species as well as between species.

Which term refers to the variety of ecosystems within a region?

ecosystem diversity. the variety of ecosystems within a given region.

Which type of habitat would have greater species diversity?

Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.

Which is a better index of diversity?

As for accounting diversity in any number of sites, Shannon-Weiner Index has been considered to be a better index as compared to Simpson’s index. In fact Simpson index is considered more as a dominance index as it accounts proportion of species in a sample.

What is the relation between habitat diversity and species diversity?

The habitat diversity effect states that as habitat area increases, the variability of structures within the habitat is likely to increase and therefore support a greater variety of species.

Why is species diversity important?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

What is unique about ecosystem diversity?

Ecological diversity can also take into account the variation in the complexity of a biological community, including the number of different niches, the number of trophic levels and other ecological processes.

What is basic habitat diversity?

Thus, habitat is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term habitat-type is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity.

What is Habitat short answer?

A habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive. For an animal, that means everything it needs to find and gather food, select a mate, and successfully reproduce. The main components of a habitat are shelter, water, food, and space.

What are the different types of habitat?

The two main types of habitats are terrestrial, or land habitats and aquatic, or water, habitats. Forests, deserts, grasslands, tundra, and mountains are just a few examples of terrestrial habitats.

What is Habitat short answer Class 6?

The place where organisms live is called habitat. Habitat means a dwelling place (a home). The habitat provides food, water, air, shelter and other needs to organisms.

What do you mean by acclimatization Class 6?

Answer: The process of changes that can occur in an organism over a short period of time that helps it to adjust to its surroundings is known as acclimatisation. Adaptation are the changes in an organism over a long period of time, whereas acclimatisation are changes over a short period of time.

What do you mean by Habitat Class 6?

The place (or surroundings) where a plant or animal lives is called its habitat. A habitat provides food, water, air, light, shelter (protection), and a place for breeding to the plants and animals living in it.

What is the best description of an adaptation?

“Adaptation is the physical or behavioural characteristic of an organism that helps an organism to survive better in the surrounding environment.” Living things are adapted to the habitat they live in. This is because they have special features that help them to survive.

Is camouflage a behavioral or physical adaptation?

Camouflage is a physical adaptation in which the animal’s body is colored or shaped in such a way that enables the animal to blend in with its surroundings.
