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

What is natural is usually healthier‚ and people who become vegetarians frequently report a feeling of increased energy and well being. There are also environmental

Many of these animals‚ such as woodpeckers and skunks‚ eat insects‚ while others‚ such as racoons‚ foxes‚ and snakes‚ eat the small rodents and frogs. The small carnivores have 600 kilocalories per square kilometer per year to eat‚ but‚ again‚ nine tenths of these Kilocalories are used up in keeping the

There are several kinds of organisms‚ such as bacteria‚ fungi‚ termites‚ grasses‚ trees‚ herbivores/omnivores‚ carnivores and scavengers‚ which can be found in the African Grasslands. The decomposers are living things (often fungi‚ insects or bacteria) that break down dead animals or plants and animal wastes to obtain energy and nutrients. The producers are plants
