Question 1

What is a quadrat?

Answer 1

A square frame of known area used for sampling the abundance and distribution of slow or non-moving organisms.

Question 2

When do you count a organism?

Answer 2

When it is half or more inside the quadrat square.

Question 3

What do you use Transect for?

Answer 3

To see the number of organism change as we move across a habitat.

Question 4

What is a Transect?

Answer 4

It is a line e.g a tape or piece of rope used to measure.

Question 5

What is a community?

Answer 5

A group of organisms interacting in a similar area

Question 6

What is a trofic level

Answer 6

The feeding levels in the food chain

Producer
Primary consumer
Secondary consumer
Tertiary consumer

Question 7

Why is energy lost in the food chain?

Answer 7

Energy is lost through respiration,movement and can not all be absorbed so the predator receives less energy each time

Question 8

Where is the most energy lost on a food triangle

Answer 8

From the sun to plants

Question 9

What is adaptation?

Answer 9

Adaptation is the special features that make an organism well suited to its environment

Question 10

What do animals compete for?

Answer 10

• mates
• food
• territory
• water

Question 11

What do plants compete for?

Answer 11

• nutrients
• water
• light

Question 12

What happens to the carbon in an organism when it dies?

Answer 12

It is released into the atmosphere

Question 13

Biological process that produces carbon dioxide?

Answer 13

Respiration

Question 14

How do humans contribute to carbon emissions?

Answer 14

Respiration
Burning fossil fuels
Cars

Question 15

What is interdependence?

Answer 15

Depending on other organisms for survival - in an ecosystem this is critical - if an organism dies out the predators will also die out

Question 16

What does biotic mean?

Answer 18

The variety of all the different species of organisms on earth, or in an ecosystem

Question 19

Is a great biodiversity good?

Answer 19

It is good

It reduces the need for one species for food so there is less likely to be loss of species

Question 20

How does acid rain form?

Answer 20

Its caused by chemicals like sulfur dioxide and nitrogen oxides being released into the atmosphere and reacting with water to create acid rain.

Question 21

What is a peat bog?

Answer 21

a wet spongy ground made of decomposing vegetation with poor drainage.

Question 22

Why are peat bogs destroyed and why is that bad for global warming?

Answer 22

They are destroyed to be used as fuel but it limits biodiversity due to the large amount of organisms living in them.
