This category is for questions about biodiversity, or species diversity, which is composed of genetic, species, and ecosystem diversity.

How does evolution explain biodiversity?

Evolutionary theory explains virtually everything about the diversity of life, everything we know about life, of extant forms as well as extinct. As the geneticist Theodosius Dobzhansky wrote: nothing in biology makes sense except in the light of evolution.

What are some practical reasons for preserving biodiversity?

Biodiversity
  1. Self preservation - The term "biodiversity" obviously includes us. We evolved in an environment of huge diversity, and if we diminish that diversity enough, we won't survive as a species either. Also, there are many life-saving drugs which have been found in plants, particularly in the rainforests. Taxol for ovarian cancer is one of them. When rainforest is cleared (without even being studied), native plants are lost forever- and a potential new drug with it.
  2. Biodiversity and the general health of the planet are one and the same, and we owe it to our children and grandchildren the chance to live a decent life on a habitable planet. We're only just beginning to understand the interconnectedness of nature, and the loss of one species can directly lead to the extinction of many more, and the loss of whole ecosystems. We are in the midst of a mass extinction, caused by us, which started about 10,000 years ago with the invention of agriculture and the use of fire, but it has greatly accelarated in the last few centuries, and the rate of species loss now is greater than it was 65 million years ago, when the dinosaurs disappeared. We have the intelligence to minimise and repair the damage we do to nature , and we have a moral obligation to do it. This is not "our" planet to exploit as we please.
  3. It might sound emotional, but every plant and creature on this earth is unique and beautiful, and to lose any one of them forever through our own actions (mostly avoidable) is a terrible shame. Our grandchildren seeing only photos of them is a sad thing to contemplate.

Name three main groups within the kingdom protista. What characteristics distinguish each group from the other two?

Algae-plant like

Fungi- slime mole and water mold

Protozoa-1st animal like .... Classified by means of locomotion!

What is the scientific definition of community?

A group of plants and animals living and interacting with one another in a specific region under relatively similar environmental conditions.

The region occupied by a group of interacting organisms.

How would you describe an ecosystem with low biodiversity?

What supplies organisms with the food energy and other resources needed to live?

Organisms obtain food energy and other resources necessary to live through the process of consuming other organisms or organic matter in their environment. This can include plants obtaining energy from the sun through photosynthesis or animals obtaining energy by consuming plants or other animals.

What are the factors that affect an area biodiversity?

The environment, climate, and other plant/ animal life that is around. Plants and animals adapt to their habitat which involves the annual climate patterns, where it lives, and the plant and animal life that surrounds it.

Why is there so much biodiversity in the intertidal zone?

Life is very diverse and abundant in the Littoral zone because it has the right conditions. There is a lot of space, the perfect warm temperature, and a lot of food available.

Why does the Calvin cycle need the light reactions to keep going?

The Calvin cycle itself does not need light.

The Calvin cycle, also called the light independent stage of photosynthesis, uses ATP (energy) and NADPH (hydrogen) to convert carbon dioxide into carbohydrate (sugar). These reactions do not need light and can take place in the dark.

However in a plant the ATP and NADPH are produced by the light-dependent stage of photosynthesis. To produce these substances light is needed.

So although the Calvin cycle does not need light itself it does need substances made using light.

Why is maintaining biodiversity important?

That way if there is a loss of one entire species entire ecosystems aren't effected so heavily, also it is what keeps life going.

According to the competitive exclusion principle two species cannot continue to occupy the same?

According to the competitive exclusion principle, two species cannot continue to occupy the same ecological niche in a community because one will outcompete the other leading to the elimination of the less adapted species.

What reduces the biodiversity of US?

How biodiversity is linked to us?

it affects us by the climate change and the animals.

How do humans affect the biodiversity of the ecosystem?

Population growth can affect biodiversity because the more people there are; the more space and resources are needed. Trees are cut down and habitats destroyed because of wood and other resources such as medicine are needed as well as to make space for shelter.

What are the different strategies and approaches of biodiversity conservation?

How does the purpose of the Krebs cycle differ from the purpose of the Calvin cylce?

The Krebs Cycle's purpose is to produce ATP that cells can use, occurs in animal cells. The Calvin Cycle is in chloroplasts and is used to produce glucose for cells.

Explain why wetlands generally have a high level of biodiversity?

Each organism in an ecosystem relies on many other organisms in order to survive. If even one species disappears, many other species are harmed by that disappearance. If you lose several or many species, then you might lose even more species, simply because those species can't survive without the ones that died out. Then even more species suffer and may disappear, and if enough very important species die out, the whole ecosystem can collapse.

How does biodiversity depend on the species ability to reproduce?

Environments are constantly changing, so the organism must adapt. Sexual reproduction ensures genetic diversity in the progeny. If one or a few of the progeny have new traits that can help it survive in its changing environment, it is more likely to reach adulthood and reproduce.

If a species becomes isolated, or reproduces asexually it will not adapt to its environment, its traits will be exact copies of its parents and the species will eventually go extinct, that particular scenario only works in areas where the environment is stable and not subject to change.

How do seed banks preserve biodiversity?

gene banks preserve genes of different organisms. If a particular type of organism becomes extinct its genes are preserved in these banks.There are many forms of gene Banks eg:seed bank.If a type of seed becomes endangered or extinct due to the use of hybrid varieties or misuse they would be preserved in these type of gene banks .thus we can prevent their extinction

What are the major threats to your biodiversity?

Tundra (specifically arctic tundra with permafrost) and rainforest are sometimes considered endangered biomes. Tundra because it is easily affected by short, warm winters, and rainforest because of human use issues.

Some other biomes have also been called "endangered". For example, the deciduous forest biomes in England and North America were almost lumbered and farmed away. No biome can actually become "endangered", because they are all created by the geology and meteorology of the area. For example, if the Earth were tipped on its side and the Arctic became the equator, all existing arctic tundra would vanish; however, the new Arctic would eventually become deforested, and populated by only short grasses, lichens, and mosses, re-creating the arctic tundra biome.

Actually, if the Earth were tipped on its side, with its axis in the ecliptic, then we would probably see some entirely new biomes. One based on constant sun for six months and constant darkness for six months, and some others based on varying between 12 hour days and constant twilight.

Which biome would contain the most biodiversity in deciduous tree species?

cutting trees for home purpose and some animal becoming extinct cause of the loss of their habitat i like fried chicken. and pototos
