Energy flow between trophic levels is another ecological concept. Trophic levels are the feeding position in a food chain. This food chain involves primary producers‚ herbivores‚ primary carnivores‚ and more. Plants are producers and in the first trophic level‚ herbivores form the second level‚ and carnivores from third and fourth trophic levels. As only small amount of energy is transferred to the higher level there are fewer organisms in higher levels. Limiting factors is the third ecological

Discuss the evolutionary explanations of functions of sleep. (24 marks) The evolutionary theories suggest sleep has evolved because it gives an animal a greater chance of survival when in a dangerous environment. They also suggest that sleep has evolved because it conserves energy and coincides with their eating habits. The evolutionary explanation (also referred to as the ecological approach) is based on the observation of animals in their natural environment. The evolutionary approach to

Therefore‚ on hot days‚ we can see dogs or tigers sticking out their tongues‚ sweating perspiration (not saliva); whereas humans as well as vegetarian animals sweat through the pores on the skin. Normally‚ carnivores’ bowels are three times their lengths; if a tiger is one meter long

Beyond that‚ too‚ is the fact that herbivores (and many omnivores) rely on plant life for sustenance‚ and the carnivores (and any omnivores) rely on eating the herbivores (and smaller carnivores/omnivores) for their own continued life - so‚ without so many plants‚ there’d be far fewer animals as well (and let’s not even begin on how that would affect the ecosystem(s) as a
