Answer: High temperature (heat) and Drought (shortage of water)
Explanation: Clumped dispersion arises as a result of an uneven distribution of food and/or other resources in the environment. It can be caused by social relationship between individuals and clumped dispersions may arise from habitat diversity or a group of species such a pride of lion or herds of elephants.
Factors that brings about high population density and clumped dispersion patterns includes high temperature and water drought. These may lead to high population density and clumped dispersion patterns in the savannah of Africa.
