Q

anaerobic respiration

A

Chemical reaction that takes place without oxygen. Glucose is converted into lactic acid and energy is released.

Q

haemoglobin

A

The substance in blood that carries oxygen around the body.

17
Q

interdependence

A

The way in which living organisms depend on each other to survive, grow, and reproduce.

18
Q

magnesium

A

A mineral needed by plants for making chlorophyll.

19
Q

niche

A

A particular place or role that an organism has in an ecosystem.

20
Q

nitrates

A

Minerals containing nitrogen for healthy growth.

21
Q

oxygen debt

A

Extra oxygen required after anaerobic respiration to break down lactic acid.

22
Q

phosphates

A

Minerals containing phosphorus for healthy roots.

23
Q

photosynthesis

A

The process plants use to make their own food, glucose. In photosynthesis, carbon dioxide and water react together to make glucose and oxygen.

24
Q

plasma

A

The liquid part of blood, which carries carbon dioxide to the lungs where it is exhaled.

25
population
The number of plants or animals of the same type that live in the same area.
26
potassium
A mineral needed by plants for healthy leaves and flowers.
27
predator
An animal that eats other animals.
28
prey
An animal that is eaten by another animal
29
producer
Organism that makes its own food using photosynthesis.
30
stomata
Holes found on the bottom of the leaf that allow gases to diffuse in and out of the leaf.
31
Equation for Photosynthesis
Carbon dioxide + water —- oxygen + glucose
32
Equation for Aerobic respiration
glucose+oxygen——carbon dioxide + water
33
Equation for Anaerobic respiration
glucose--- lactic acid
34
Equation for Fermatation
Glucose ——Ethanol + carbon dioxide
