Two species of animal are found in the same area of forest and grassland. In the spring and summer they eat the same plant food. However, in the autumn and winter one eats nuts in the forest and the other eats roots on the grassland. Both species are preyed upon by the same predator. Numbers of root-eating animals are reduced most by this, but they recover faster since they reproduce faster. What can be concluded about these two species of animals? 1 They are part of the same community. 2 They are at different trophic levels. 3 They occupy different habitats. 4 They have different niches.
