Why is earth so biodiverse?

Why is the earth so biodiverse?

Another part of the explanation of the high biodiversity of certain mountains is linked to the geological dynamics of mountain building. These geological processes, interacting with complex climate changes through time, provide ample opportunities for evolutionary processes to act.

Why is there so much diversity in life on earth answers?

Life on earth is incredibly diverse. Biological diversity is the variety of life on earth. … Biological diversity is constantly changing. It is increased by new genetic variation and reduced by extinction and habitat degradation.

When did earth have the most biodiversity?

The tendency for species diversity to be greatest near the Equator developed 34 to 48 million years ago during the Eocene Epoch, Museum scientists have found. This global distribution pattern of species is a major feature of biodiversity today.

Where does earth’s biodiversity peak?

Two of the Most Diverse Ecosystems on Earth

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.

Why is biodiversity so important?

Biodiversity is important to humans for many reasons. … Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.

What are the main causes of biodiversity loss?

CAUSES OF BIODIVERSITY LOSS

  • Climate change.
  • Pollution.
  • Destruction of habitats.
  • Invasive alien species.
  • Overexploitation of the natural environment.

What causes diversity of life?

The source of this diversity is evolution, the process of gradual change during which new species arise from older species. Evolutionary biologists study the evolution of living things in everything from the microscopic world to ecosystems.

Why is Australia so biologically diverse?

The uniqueness of Australia’s biodiversity is largely due to this continent being separated from other land masses for millions of years. … Many of Australia’s species, and even whole groups of species that comprise taxonomic families, are endemic (unique) to this continent (Table 8.1).

How has the biodiversity of Earth changed since the origin of life?

Biodiversity has drastically changed since the origin of life. The initial organism began as a prokaryote (single celled organism with out membrane bound organelles). Today, there are plants, animals, prokaryotes, fungi, etc. … today organisms are complex and there are billions of species throughout the planet.

What is biodiversity explain it?

Biodiversity is all the different kinds of life you’ll find in one area—the variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural world. Each of these species and organisms work together in ecosystems, like an intricate web, to maintain balance and support life.

What is biodiversity in simple words?

Biodiversity is the shortened form of two words “biological” and “diversity”. It refers to all the variety of life that can be found on Earth (plants, animals, fungi and micro-organisms) as well as to the communities that they form and the habitats in which they live.

Which species has most diversity?

The sponges, Poriferans, were found to have some of the greatest diversity of both body size and species, ranging from microscopic to the size of an automobile. Molluscs (snails, squid, clams, chitons), and Arthropods (crabs, insects, lobsters, copepods) also showed great diversity.

Why is the most biodiversity found near the equator?

There might be more biodiversity near the equator because it’s warmer year round, allowing organisms to continue growing. Locations away from the equator will have cold winters that will slow growth for microorganisms, plants and animals.

Why is high biodiversity advantageous over low biodiversity?

Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
