They study the environment and the organisms. (plants)

Decomposers reduce the remains of dead living things which were once alive, like dead leaves/plants (litter) and other dead animals. Decomposers break down dead living things into nutrients to add to the soil for plants to grow.

Allopatric speciation: ( other country ) A speciation event that is facilitated geographically. A population is split along geographic lines, mountains, rivers, and the now separate gene pools vary in allele frequency over time enough to , possibly, have two new species arise.

Sympatric speciation: ( same country ) An in place speciation event where a sub-population within a population begins to vary their alleles from the main population. Perhaps a slight temporal, or water level difference, or mating differences can facilitate this. This speciation event is still a matter of contreversy in biology.

Simplified explanations.

because we have only a limited amount of matter on earth

Sunlight, air water soil and space.

The abiotic and biotic factors are the parts of an ecosystem.

Cultural eutrophication is an increase in biological productivity and ecosystem succession caused by human activity. It is mainly caused by increased nutrient input into a water body. Increased productivity in an aquatic system sometimes can be beneficial. Fish and other desirable species may grow faster, providing a welcome food source. Eurtophicate produces blooms of algae or thick growths of aquatic plants stimulated by elevated phophorus or nitrogen levels. The water then becomes cloudy and faul smelling and can accelerate the aging in a body of water.

Plants and animals, a water source. Make sure there are places for smaller animals to hide. You need to be in control of the atmosphere and the temperature inside the sphere, make sure there is food for the animals. Avoid too many predators.

If this is Spore Account Name : Camelfox, You're not alone.

its the habitat were animals live

hold, tear, and pass solid food to the mouth.

The lower region will flow to the higher region as much as possible. The two sides will become equal to each other.in this process.

1. Everything is Connected to Everything Else. There is one ecosphere for all living organisms and what affects one, affects all.

2. Everything Must Go Somewhere. There is no "waste" in nature and there is no "away" to which things can be thrown.

3. Nature Knows Best. Humankind has fashioned technology to improve upon nature, but such change in a natural system is, says Commoner, "likely to be detrimental to that system."

4. There Is No Such Thing as a Free Lunch. In nature, both sides of the equation must balance, for every gain there is a cost, and all debts are eventually paid.

For some reason they are here, they live in a balanced ecosystem, unbalancing ecosystems, as we are finding out has greater ramifications than we originally thought. I guess my answer is to not mess too much with mother nature, or if you are religious do not mess with what God has created.

Respiration, then travels to the biotic part of the biosphere(through trees, etc.)

What adaptations do plankton have to help them avoid sinking in the photic zone ?

it's the plants or you can say grass

1- grass(primary producer or first step of food chain) eaten by.......

2- frog eaten by........

3- snake eaten by........

4- eagle

The Australian desert food chain is like any other. Plants produce sugars and protein from the sun. Atriplex is a common plant genus found in Australian deserts but there are many more including acacia and various grasses like nadoo. These plants act as food for animals. Because of introduced animals like camels, goats, horses and rabbits, many of the native species such as bandicoots, bilbies and native mice that would normally eat these plants are becoming endangered. There are also predators that eat these such as the dingo (wild dog) and wedge tailed eagles. When these die, their bodies fall to the ground where they are eaten by bacteria producing nutrients for the plants.

Geography is the study of the land, water, plants, animals, people, and locations of a place. A continent is one of the seven large land areas of the world.

Bees can walk or fly.

No, there will never be enough resources for everyone. This one of the reasons why money is used to make purchases.
