Answer AND Explanation:
In both plants and animals, the movement of water requires an osmotic pressure and a concentration gradient. When animals take in water by osmosis, the swell and burst. this is called haemolysis. Unlike in plants, when the cells take in water, they become turgid. The animal cells lack cell wall and thus they burst since the cell membrane is not elastic.
Its characteristic is the high temperature and the division of two seasons: rainy in summer and dry in winter. In regions affected by this type of climate, it is not possible to notice the change of seasons.
An organism may establish a definite area within the habitat and defend it from all other members of the population. The organisms which establish and defend a territory are more vigorous and better fitted members of the population. They are more assured of producing off-springs and thus perpetuating their more favourable attributes within the species.
