Solution
Different types of living things are seen in different places. Some signs of their presence are seen sometimes, even if these living things are not seen themselves. For example, partly eaten fruits. shells, fallen feathers, animal tracks, dung, droppings, nests, cocoons, eggs, honeycombs, etc. are noticed during observations. Partly eaten fruits can confirm that there were squirrels, monkeys, or some fruit-eating birds before we arrived. From the fallen feathers, one could guess about the types of birds that visited the place. We can also guess from the animal tracks, pugmarks, dung, or droppings.
