BIODIVERSITY

Biodiversity refers to the number of species in an ecosystem or the biosphere as a whole.

IMPORTANCE OF BIODIVERSITY

Biodiversity has direct economic benefits. It also provides services to entire ecosystems.

Open Ended

Multiple Choice

Biodiversity is important to keep an area (biome) healthy. In this example "Food Web A" is sustainable. Why is sustainability important for an ecosystem in "Food Web A".

If one organism is removed the food web can still operate (work) with little or no negative effect.

If an organism is removed the food web will collapse and will affect the environment.

Multiple Choice

Which biome is more likely to survive a change in the environment?

High (rich) biodiversity

Low (poor) biodiversity

Multiple Choice

Which option is abiotic?

Plants

Bacteria

Water

Fungi

Multiple Choice

Food Web B is an example of...

Low biodiversity and low sustainability. If the producer dies then all the food web will suffer.

High biodiversity and high sustainability. If an organism is removed the food web will continue with no effect.

Multiple Choice

Where does the energy from an ecosystem come from?

Trees

Sun

Plants

Water

Multiple Choice

Variation happens as a result of the exchange of genetic information as it is passed fromparent to offspring.Which of the following is true about inherited variation?

Variation can influence the resources that are available to an organism.

Variation can influence whether organisms are more likely to survive to reproduce.

Variation can influence the amount of rainfall in an ecosystem

Variation can influence the amount of available food in an ecosystem

Multiple Choice

In a population of spiders there are three different sizes: small, medium, and large.
---The large spiders are easily seen by predators.
---Small spiders have a difficult time finding food.
What will most likely happen to this population of spiders after many generations?

Small and large spiders will mutate

Medium spiders will be the most plentiful

Large spiders will learn to hide from predators

Small and medium spiders will be the least plentiful

Multiple Choice

Organisms need all of the following things EXCEPT

Food

Water

Shelter

Ability to hunt

Multiple Choice

Forests are often preserved to protect biodiversity. This helps preserve the unique characteristics of the organisms that live there. Sometimes these forests are divided into separate sections that are spread out instead of one continuous forest. This is known as forest fragmentation. Which types of organisms will be the least likely to be affected by forest fragmentation?

herbivorous birds that are able to migrate great distances

omnivores that hibernate in winter in order to conserve energy

omnivores that burrow underground deep in to the soil.

herbivorous mammals that are dependent upon specific plants for food

Multiple Choice

What would indicate that a series of fossils represent evolution?

the fossils were identical

the fossils were found in the same layers of rock

the fossils show similarities

the fossils were completely different

Multiple Choice

Change over time is

evolution

generation

growth

biogenesis

Multiple Choice

Natural selection is

survival of the fittest

humans change

two species are the same

more animals survive

Multiple Choice

This makes an organism more suited to its enviornment

species

lifespan

adaptation

mutation

Multiple Choice

Who was Charles Darwin?

A naturalist who came up with the theory of evolution

A scientist who studied plants

A geologist who looked at rocks and fossils

A paleontologist who studied dinosaurs

Multiple Choice

Which of the following is a fossil?

a plant that has recently died

a group of organisms that can reproduce

a structure or organ that no longer functions

a trace of an organisms that existed in the past

Multiple Choice

In natural selection, the selective agent is the

humans

mutations

breeders

environment

Multiple Choice

Mutations are important because they bring about

death of the organism in which they develop

genetic variation needed for a population to evolve

benefits for the individual, not for the population

Hardey-Weinberg equilibrium within a population

Multiple Choice

Natural selection results in change over time by acting on traits that are

heritable

new

mutated

better than the best

Multiple Choice

Most of the species found in fossil form are _______________.

Alive

Extinct

Multiple Choice

What is the difference between biotic and abiotic?

Biotic are non-living things

Abiotic are living organisms

Biotic is life,
Abiotic is non-living

Biotic is non-living, Abiotic is living

Multiple Choice

High biodiversity is

having a lot of the same organism.

having a few of the same organism.

having a lot of variety of different organisms.

only having one of each organism.

Multiple Choice

How do biodiversity and sustainability work together?

The lower the biodiversity the greater the sustainability.

The higher the biodiversity, the less sustainable the ecosystem

The higher the biodiversity, the greater the sustainability.

Biodiversity has nothing to do with sustainability.

Multiple Choice

A small marine area has phytoplankton as its only producer. Should the marine biologist be concerned about this ecosystem?

No the fish do not need the phytoplanton. Since there are so many fish, there is high biodiversity.

Yes, this ecosystem has low biodiversity. Without a producer the herbivores will die out leaving no food.

Yes, this system has high biodiversity; however the fish can adapt and get food from another source.

Yes, the fish will overate to get all of the phytoplankton that is left, then they will die.

Multiple Choice

When there is higher biodiversity

more organisms are likely to die because they can't adapt to environmental changes.

there is less diversity.

there is more diversity and higher sustainability of life.

there is more diversity and lower sustainability of life
