• PREDATOR - PREY CYCLE

KERBOODLE PAGES 285-289

KEY TERMS:

If circumstances are ideal a 

population will have exponential 

growth, this means it doubles 

every generation, so 2, 4, 8, 16, 

32 etc. This goes on till the 

population reaches the carrying 

capacity. 

population starts growing

exponential 

growth

carrying capacity

LIMITING FACTORS

When a population reaches the carrying capacity, the growth of the population is slowed down by the limiting factors:

• oxygen
• toxic waste
• overcrowding
• predators
• disease
• climate
• lack of shelter

POPULATION RESEARCH

When researching plants you're always use a quadrate by calculating a percentage cover.

When researching animals you use the mark, capture and release method.

Predator- prey cycle

PROJECT SPRINT 2:

• Create a predator prey cycle DIAGRAM for your apex predator and one of it’s prey. Each square must contain:
• at least one picture.
• TEXT ( min. 50 words EACH)
• If you cannot find exact numbers please do not worry! Replace it with other information.

What now?
