how animal dispersed fruits are different from wind and water dispersed fruits?
Answers
Answer:
Seeds dispersed by water are found in light and buoyant fruits, while those dispersed by wind may have specialized wing-like appendages. Animals can disperse seeds by excreting or burying them; other fruits have structures, such as hooks, that attach themselves to animals' fur.
Answer:
Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.

Examples include mangoes, guavas, breadfruit, carob, and several fig species. In South Africa, a desert melon (Cucumis humifructus) participates in a symbiotic relationship with aardvarks—the animals eat the fruit for its water content and bury their own dung, which contains the seeds, near their burrows.
There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus.
Why can't all seeds be dispersed by water?
Answer. all seeds cannot be dispersed by seeds as for this they need to be light weight and have hairs or wings so that wind can carry them off. all seeds don't have all these features so they are dispersed by different methods as per their characteristics.
