Environment & Responses
Organisms need to survive and reproduce (contributing their alleles into the gene pool) in order to be successful.
Environment & Responses
Organisms need to survive and reproduce (contributing their alleles into the gene pool) in order to be successful.
Animal responses are adaptations for survival and reproduction through:
- Finding favourable conditions and avoiding unfavourable

Organisms need to survive and reproduce (contributing their alleles into the gene pool) in order to be successful.
Animal responses are adaptations for survival and reproduction through:
- Finding favourable conditions and avoiding unfavourable
- Obtaining nutrients, energy, water and oxygen

Animal responses are adaptations for survival and reproduction through:
- Finding favourable conditions and avoiding unfavourable
- Obtaining nutrients, energy, water and oxygen
- Reducing competition

Organisms need to survive and reproduce (contributing their alleles into the gene pool) in order to be successful.
Animal responses are adaptations for survival and reproduction through:
- Finding favourable conditions and avoiding unfavourable
- Obtaining nutrients, energy, water and oxygen
- Reducing competition
- Avoiding predation/reducing herbivory (if plant)
Environment & Responses
Organisms need to survive and reproduce (contributing their alleles into the gene pool) in order to be successful.
Animal responses are adaptations for survival and reproduction through:
- Finding favourable conditions and avoiding unfavourable
- Obtaining nutrients, energy, water and oxygen
- Reducing competition
- Avoiding predation/reducing herbivory (if plant)
- Finding a mate (same species!)
Abiotic Factors – non-living
Include temp, light intensity, humidity, wind speed, salinity, pH, water, oxygen, carbon dioxide and mineral levels, and substrate.
Abiotic Factors
Include temp, light intensity, humidity, wind speed, salinity, pH, water, oxygen, carbon dioxide and mineral levels, and substrate.
Eg – some abiotic factors are terrestrial = humidity and wind. Some are important in water = pH, salinity etc.

Organisms can only live in areas where the abiotic factors are within the range of the physiological tolerance.

Organisms can only live in areas where the abiotic factors are within the range of the physiological tolerance.
Eg – If pH, salinity, light intensity etc are outside the range for Elodea (pond weed) it will die off.

Many abiotic factors change in a rhythm = predictable manner. Both plants and animals can detect these changes and respond accordingly.
Biotic Factors - living
Are the influences and interactions with other living organisms.
- Competition (intraspecific = within species & interspecific = between species)

- Exploitation (predation, herbivory, parasitism)
