Can be classified as: 1. Interspecific 2. Predation 3. Symbiosis
It is competition between members of different species
The weaker competitor declines Some organisms may migrate to another habitat
It is a (+/−) interaction between species one organism, directly feeds upon another E.g. weevils eating seeds
It results in the population density of one species (predator) increasing while the other (prey) decreases.
Some predator- prey relationships are steady and show a cyclical pattern. The graph is called a sinusoidal curve.
Are used by insects, plants & animals It protects them from predators
Some plants: have spines, hooks or needles or use chemicals they can make themselves distasteful Or mimic the growth hormone of an insect…killing it
Some animals: have horns
