Ecosystems

Question 1

What are ecosystems made up of

Answer 1

Communities of organisms that interact with their environment

Question 2

What is interdependence?

Answer 2

One species rely on each other to survive so changes to a population can have a effect on other species

Question 3

What is an extremophile

Answer 3

Bacteria who are adapted to live in extreme conditions

Question 4

What do indviduals of The Same species that can breed together produce

Answer 4

Fertile offspring

Question 5

Where do organisms live

Answer 5

Hábitats

Question 6

What do you call individuals from one species living in the same habitat

Answer 6

Population

Question 7

What do you call populations of all different species that share a habitat?

Answer 7

A community

Question 8

What is an ecosystem affected by ?

Answer 8

Abiotic and biotic factors

Question 9

Abiotic factors

Answer 9

Light intensity, temperature, moisture/water levels, pH of the soil, soil mineral levels, direction and intensity of the wind, levels of carbon dioxide and levels of oxygen

Question 10

How does light intensity affect an ecosystem?

Answer 10

Increasing light intensity will increase the rate of photosynthesis in plants

Question 11

How does temperature affect ecosystem?

Answer 11

Animals and plants grow the best at their optimum temperatures

Question 12

How does moisture and water levels affect ecosystem?

Answer 12

Plants and animals require the correct amount of water

Question 13

How does the pH of soil affect ecosystems?

Answer 13

Different plants will grow fast in different soil acidities

Question 14

How does soil mineral levels affect the ecosystem?

Answer 14

Plants require lots of minerals to grow healthy

Question 15

How does the direction and the intensity of the wind affect ecosystems?

Answer 15

Wind speed can affect transpiration and photosynthesis rates in plants. Organisms may also move to find shelter from the wind.

Question 16

How do carbon dioxide levels affect ecosystems?

Answer 16

Plants need lots of carbon dioxide for photosynthesis

Question 17

How do levels of oxygen affect ecosystem?

Answer 17

Some aquatic animals can only survive if there’s lots of oxygen dissolved in the water

Question 18

Name biotic factors

Answer 18

Availability for food, introduction of new predators, introduction of new pathogens and competition

Question 19

How does availability of food affect ecosystems?

Answer 19

Organisms require food to supply and reproduce. Population thrive when there is lots of food available.

Question 20

How do new predators affect an ecosystem?

Answer 20

In balances communities, there is enough prey for the predators to feed on if new predators arrive this balance can be shifted and there may not be enough prey to go around

Question 21

How do new pathogens affect an ecosystem?

Answer 21

Populations will have no immunity or resistance to new disease which can lead to an increase in death until resistance evolved

Question 22

How does competition affect an ecosystem?

Answer 22

Different organisms and the same resources so if some organisms are better acquiring the shared resource and other they will out compete the less adapted organism until there is no longer enough of them to breed.

Question 23

What are structural adaptations?

Answer 23

Physical features

Question 24

What are behavioural adaptations?

Answer 24

Adaptations that cause an organism to act/behave in a certain way

Question 25

What are functional adaptations?

Answer 25

Processes that occur inside of an animals body
