Biodiversity 1.1

Question 1

What is biodiversity?

Answer 1

Biodiversity is the combination of two words bio+ diversity. Biodiversity refers to all the living organisms on Earth. Scientists study biodiversity in small groupings in order to track changes.

Question 2

What are the three types of biodiversity?

Answer 2

The three types of biodiversity include;

a. ) Ecosystem Diversity- The number of different ecosystems that fall within an area.
b. )Community Diversity- The number of different communities that make up an ecosystem.
c. )Genetic Diversity- The variations between members of single species.

Question 3

What is the definition of population?

Answer 3

Populations refers to the group of individuals of the same species living in the same area.

Question 4

What is the definition of community?

Answer 4

Group of populations of different species living in the same area.

Question 5

What is the diversity between ecosystems?

Answer 5

Biotic - living
Abiotic - non living
Biotic & Abiotic interact
Abiotic - air, water, sunlight
There are differences between ecosystems

Question 6

What is the diversity within ecosystems?

Answer 6

Population - same species live in an area
Ex - trees, grasses, magpies
Community - different species live in an area
The community is the biotic part of an ecosystem

Question 7

What is the diversity between species?

Answer 7

A species is a group of organisms that has the same basic structure.
Looking closely at populations, there are variations within. These are caused by subtle variations in the cells of the organisms.
Some variations are not visible.
Ex - human blood types

Question 8

What is species distribution?

Answer 8

Species on our planet are not distributed evenly.
Areas around the equator have the greatest number of plant species
Plants & animals species are greater in tropical environments.
Therefore the tropical rain forests closest to the equator have the greatest biological diversity.
When you move north, the biological diversity weakens.

Question 9

How do you classify animals?

Answer 9

To classify animals, we use something called the Linnaeus’s naming system. In this system, two words name name each living thing: the first word indicates the name of the genus (category) to which the organism belongs and the second word indicates the particular species.
This system arranges species into groups based on their physical structure rather than on their habitat.
