Explain predation.

Explanation

Predation :
`cdot` Predation is a type of interaction in which a large organism called predator of higher trophic level feeds on another organism called prey of lower trophic level.
`cdot` In this type of interaction, one of the partner.s (predator) is benefitted while the prey is harmed.
Role played by predators :
`cdot` They act as links for energy transfer across trophic levels.
`cdot` They keep prey populations under control.
Defences developed by animal preys against predators :
`cdot` Some show cryptic colouration to avoid being detected esaily by the predator.
`cdot` Some are posionous and some are highly distasteful and therefore are avoided by the predators.
Defences developed by plant preys against predators :
`cdot` Thorns ( Acacia, Cactus) are morphological means of defence.
`cdot` Many plants produce and store chemicals like nicotine, caffeine, quinine, strychine, opium, etc. that make the herbivore sick when they are eaten, inhibit feeding or digestion, disrupt its reproduction or even kill it .
