a collection of all organisms.

Question 7

What is a population? Give an example of one that would live in a forest.

Answer 7

All members of a particular species that live in the same area. Ex: Foxes

Question 8

What factors affect the size of a population?

Answer 8

Is abotic and botic factors as well as birth and death rates.

Question 9

Describe what a graph looks like when a population grows exponentially?

Answer 9

This growth is when there are unlimited resources this growth typically looks like a J.

Question 10

Why does exponential growth occur?

Answer 10

This occurs when there is unlimited resources .

Question 11

Describe what a graph looks like when a population grows logistically?

Answer 11

This growth looks like a S.

Question 12

Why does logistic growth occur? What is carrying capacity?

Answer 12

Logistic growth occurs when there are limited resources . Carrying capacity is when the maximum population that can be supported by the resources.

Question 13

What type of growth pattern do humans follow? Give some reasons why.

Answer 13

Humans follow the logistic growth due to there being limited resources.

Question 14

What does a primary consumer eat? Is a primary consumer an herbivore or carnivore?

Answer 14

Primary consumer eat Producers . They are then herbivore due to herbivore only eating plants.

Question 15

What does a secondary consumer eat? Is it an herbivore or carnivore?

Answer 15

Secondary consumers eat Primary consumers . They are carnivore due to carnivore eating animals.

Question 16

Write the following in order from who has the most energy to the least: secondary consumer, primary consumer, producer, tertiary consumer.

Answer 16

Producers , Primary consumers , Secondary consumers , and Tertiary.

Question 17

If the producer has 2000 kcal of energy available, what is the amount of available energy at each level?

Answer 17

Producers - 2000
Primary -200
Secondary - 20
Tertiary - 2

Question 18

Explain what would happen to the energy pyramid if the primary consumer dies off. How would the producer be affected? How would the secondary consumer be affected?

Answer 18

The Producers increase and the secondary decrease a bit.

Question 19

Autotroph - Producers
Heterotroph- Consumers

Question 23

What is the conservation of matter?

Answer 23

The process in which matter was transferred to energy and back to matter again.

Question 24

Where in the plant cells does photosynthesis take place?

Answer 24

chloroplast is where it takes place.

Question 25

Outputs: Water and Energy .

Question 26

Give an example of an organism that does cellular respiration?

Answer 26

Animals, Plants and Fungi.

Question 27

What is ATP? Explain the cycle of ADP and ATP.

Answer 27

ATP is the source of energy for use and storage at cellar level. ADP is continually converted to ATP by the addition of phosphate.

Question 28

Explain how energy flows in an ecosystem.

Answer 28

The way it flows is by going from producer to consumers . The energy that exists from the food is then converted to chemical energy by the photosynthesis.

Question 29

Explain how matter flows in an ecosystem.

Answer 29

By an organisms eating another the matter, carbon , or nitrogen transfers from one another. This then goes through the cycle of producer to consumer.

Question 30

List and explain 9 ways humans impact ecosystems and affect biodiversity

Answer 30

Deforestation , global warming , pollution , burning fossil fuel , building houses .

Question 31

What gases make up our atmosphere?

Answer 31

78% nitrogen , 21 % oxygen gas , 1 % CO2 and other gasses

Question 32

What is the greenhouse effect?

Answer 32

The amount of certain gases in the atmosphere are the earth insulated .

Question 33

What are greenhouse gases? How do they affect our atmosphere?

Answer 33

They are what keep the light inside to keep the earth warm . It affects the atmosphere by keeping in the heat in the atmosphere that would then cause global warming.

Question 34

What is climate change? What are some indicators of climate change?

Answer 34

A change in any aspect of the earths climate.
Average temperature rising , frequency of heat waves increasing , increasing sea surface temperature,

Question 35

What is global warming?

Answer 35

Gradual increase in the temperature of the earth and its atmosphere due to the enchanted greenhouse effect.

Question 36

How does the burning of fossil fuels affect carbon emissions and global warming?

Answer 36

The way it affects it is because of humans burning fossil fuel it increasing the carbon in the air which then increase the green house effect.
