Brainstorm and create a list of 4 human activities that interfere with ecosystems, food chains and food webs. for each explain how it happens, why we do it, and mention short and long term effects

The humans are the dominant consumers. They influence food chains and food web through agriculture, production of energy, habitat destruction, pollution, hunting, and overfishing. This is generally done in order to fulfill the demands for food and shelter along with the growth of population. In long term, it influences aquatic and soil ecosystems.  

In case if due to human activities if one community of animals gets extinct then there will be a chain reaction of animals getting extinct. The animals live in harmony to thrive and without which it will proliferate into more extinct animals. Ultimately the majority of the animals will no longer be alive.  

they fuse to form they have half as many chromosomes as a somatic cell of the same individual. b
