Biodiversity

Which of the following describes pioneer species?

• this type starts with bare rocks and no soil is present to create a new community

• this type starts with soil and involves replacing an old community

• the process of order changes of of species during the formation of a community

• the first species to appear and can help with soil formation

Regions of Earth that are defined by their climate and the unique plants & animals that live there

• biome

• ecosystem

• environment

• niche

The number of different species of plants and animals in an area

Why is biodiversity important in an ecosystem?

• Number of offspring for a species increases

• Creates more competition for resources among species

• Number of organisms in the food pyramid will increase at each trophic level

• Leads to stability of an ecosystem, which enables it to withstand a distrubance

In what way is under a rock a mircrohabitat?

• It supports a distinct population of organisms

• It provides camouflage for particular organims to protect them

• It enriches the soil

• It is a large community of organisms that occupy a major habitat

The more diverse an ecosystem is -

• the more threatened its populations are

• the more similar the species will be

• the more sustainable it is

• the fewer varieties of species are present

Which of the following is a direct consequence of reduced biodiversity?

• Enhanced ecosystem services

• Increased genetic diversity

• Loss of ecosystem stability

• More food resources

How does biodiversity contribute to the sustainability of an ecosystem?

• By increasing the number of predators

• By providing a variety of genetic resources

• By reducing the number of species

• By increasing the population of a single species
