Environmental factors can cause evolutionary changes within populations. Species are adapted to particular abitioic conditions. A factor that affects an organism’s survival or reproduction, changes the population’s gene pool. E.g. an ecological effect is the decrease in population size which causes an evolutionary effect of camouflage. (2) Tropical forests grow fast to compete for light. (3) Desert plants are designed for water conservation as they always have scarcity. The environment includes both abiotic components (non-living e.g. temperature, light, water nutrients, disturbance) and biotic components (living e.g. all organisms aka biota) o A population is a group of individuals of the same species living in a particular
