"Natural selection and speciation leads to evolution." Justify this statement . |
| Answer» Reproductive isolation takes place when the given group of species are not allowed to mate with each other due to physical barrier, and speciation is said to occur when a single species divide into group and become a two or more separate species, which can no longer interbreed with each other.Reproductive isolation is required for speciation to occur because if it do not occur the member of the same species continue to interbreed with each other, and because of this mating there are chances that any beneficial mutation may occur, which will cause evolution in the population. | |

What is Ten percent law? Describe how energy and material passes from one trophic level to another. |
| Answer» As we pass from one trophic level to the next, only 10% of energy is transferred from the first trophic level to the next. This is because a lot of energy is lost to the surroundings and rest is utilised by the organism.We can understand this better using an example.When green plants are eaten by primary consumers, lot of energy is lost as heat to the environment. Some energy is used by the consumer into doing work and digestion whereas rest is used for growth and reproduction. About 10% of the eaten food is turned into its body and made available to the next level of consumers. So the actual energy passing to the next trophic level is only 10%.\xa0Grass -> Grasshopper -> Frog -> snake -> hawkHere, a part of the solar energy is captured by grass which uses it to produce food. About 10% of this captured energy is passed on to grasshoppers. Here, large amount of energy is lost as heat, some goes into digestion and doing work and rest towards growth. Again 10% of the food eaten by the grasshopper is made available to the next trophic level, comprising\xa0of frogs. In this way energy flows further from frog to snake and from snakes to the final trophic level, made up of hawks..Another example would beDead organic matter -> Microrganisms like bacteria, fungi etc. -> Detritivores like earthworms, nematodes etc. -> Predators like snakes, frogs etc. | |
