LESSON 1: D1 - Diversity and Classification Flashcards
What makes an ecosystem stronger than another?
Biodiversity
What are the 3 features within biodiversity that help ecosystems?
- Ecosystems
- Speices
- Genetics
How do speices keep a ecosystem stronger?
-Speices that survive longer can continue intercations that benfit the ecosystem
What makes a strong ecosystem?
One that is able to withstand natural disaters, have interconnected relationships that helps the ecosystem flourish.
How do genetics make an ecosystem stronger
Better genetics allow speices to live longer and survive in harsh conditons
What is biodiversity?
Biodiversity is a measure of the variety and number of life forms on Earth
What is a speices?
A species is a group whose members can successfully mate under natural conditions and whose offspring can do the same
Not only is there biodiversity or different spieces there is also…
- Diversity of interactions between species
-Diversity of habitat or structural diversity
What could loss of biodiversity mean?
- Threaten our food supply
- Eliminate sources of natural medicines
- Have a significant impact on tourism and forestry
- Impact or seriously disrupt biogeochemical cycles
What are two examples of biogeochemical cycles?
- carbon cycle
- water cycle
TRUE OR FALSE:
Earth has a carry capacity
True
What two factors caused by humans could affect biodiversity?
Resource management and human population
(More humans limit species richness because no two things can occupy one place)
How are human population growth and spieces richness connected?
- If populations growth stunts then speicies richness increases
What are the two catagories of human meditated loss of biodiversity
Local and Global
What are the 4 local chnages?
- Land use changes
- Pollution
- Resources explotation
- Exoctic speices
