Which is not an example of a biome? (hint: biomes are very large ecological areas on the earth’s surface, with fauna and flora (animals and plants) adapting to their environment.)

a: forest
b: desert
c: grassland
d: lake

Explanation:

Biomes: Temperate Deciduous Forest, Coniferous Forest, Woodland, Chaparral, Tundra, Grassland, Desert, Tropical Savanna

A lake is not a biome. A lake can be found in a biome, but a lake is not itself a biome. A biome is a community of plants and animals that have common characteristics for the environment they exist in. Yes, similar species can be found living in a lake, but a lake can be found in a particular biome where there are lots more of the same species.
