Demonstrate Understanding of Adaptation of Plants or Animals to Their Way of Life
The process of change by which an organism or species becomes better suited to its environment
An inherited feature of an organism that enables it to survive and reproduce in its habitat
The end result of the evolutionary changes (genetic mutations) that a species has gone through over time

There are 3 types of adaptations
1. Behavioural - the way an organism reacts/responds to stimuli
2. Structural - the way an organism is built/made
3. Physiological - something the organisms' body does/produces

1. Behavioural - the way an organism acts in response to something,
e.g. desert plants have flowers that open at night because there are more pollinators active during the cool hours. 2. Structural - physical features of an organism, e.g. thorns on a African bush to protect it from its prey. 3. Physiological - those involving physiological processes, e.g. the female mantis produces a frothy liquid to surround and protect the groups of eggs she lays. |
The two selection pressures that have contributed to the adaptations we see in plants today
1. The need to conserve water
2. To protect against efficient herbivores
