Biodiversity
This category is for questions about biodiversity, or species diversity, which is composed of genetic, species, and ecosystem diversity.
1,421 Questions
Why is species richness more important than abundance?
species richness is related to species diversity. It refers to the number of different species present in an environment.
species evenness refers to how close in numbers each species in an environment are.
For example an environment with three species A, B, C
A has 56
B has 54
C has 55
This environment is low in species richness but high in evenness.
Why are lobster important in biodiversity?
Every animal is important to an ecosystem in some way. Lobsters help clean debris off ocean floors and feed on weaker animals.
What ecosystems has high biodiversity?
Forest and jungle ecosystems, the largest ecosytem is the Amazon Rain Forest in South America
Before the calvin cycle begins where is the energy stored?
The energy needed for the Calvin cycle is stored in the form of ATP and NADPH molecules, which are produced during the light-dependent reactions of photosynthesis. These molecules provide the energy required for the Calvin cycle to convert carbon dioxide into carbohydrates.
Terrestrial refers to things having to do with the land. Biodiversity is the variation of life forms within a given ecosystem or biome. Combine the two, and there you go! (Terrestrial Biodiversity: the variation of life forms within a given ecosystem or biome that refers to species that inhabit the land.)
What is the molecule that's responsible for unity and diversity of life?
DNA is the molecule that is responsible for unity and diversity of life .
Where is earth's biodiversity the greatest?
Earth's biodiversity is greatest in tropical regions, particularly in areas like the Amazon rainforest, the Congo Basin, and Southeast Asia. These regions boast a high variety of species due to their warm climates, abundant rainfall, and complex ecosystems. Additionally, coral reefs are also recognized as biodiversity hotspots, hosting a vast array of marine life. The combination of diverse habitats and favorable environmental conditions contributes to the rich biodiversity found in these areas.
What does net primary productivity result in?
is the production of organic compounds from atmospheric or aquatic carbon dioxide, principally through the process of photosynthesis, with chemosynthesis being much less important. All life on earth is directly or indirectly reliant on primary production. The organisms responsible for primary production are known as primary producers or autotrophs, and form the base of the food chain. In terrestrial ecoregions, these are mainly plants, while in aquatic ecoregions algae are primarily responsible. Primary production is distinguished as either net or gross, the former accounting for losses to processes such as cellular respiration, the latter not.
What are two characteristics that distinguish fungi from plant?
Fungi can be further classified based on a number of characteristics. These include the size and shape of spores or fruiting structures, biochemical and physiological traits, and reproductive structures.
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?
- 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.
- 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.
- 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.

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.
Where is the most biodiversity where is the least biodiversity?
the lowest biodiversity is in the polar regions!
#NEW~NEW!!How would you describe an ecosystem with low biodiversity?
hindi ko rin po alam kung ano ang sagot hehehehe tanong mo nalang sa pagong
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.

and How_do_the_lightdependent_reactions_differ_from_the_calvin_cycle
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.
