Final answer:
The statement that the desert, the swamps, and the rainforest are all part of the big biosphere is true. The biosphere includes all life-containing areas of Earth, encompassing a variety of biomes with distinct plant and animal communities.
Step-by-step explanation:
The desert, the swamps and the rainforest are indeed all part of the big biosphere. The biosphere refers to the parts of Earth that contain life, encompassing diverse ecosystems such as deserts, swamps, and rainforests. Each of these environments is a biome, which is a group of similar ecosystems that share common abiotic factors and primary producers. For instance, while the Sahara Desert in northern Africa and the rainforests in northeastern Australia are different biomes because of their unique plant and animal communities, they are both part of the global biosphere.
Biomes like the tropical rainforest and deserts have distinctly different communities due to the abiotic factors like climate and soil types. Nonetheless, despite their differences, they coexist within the same biosphere, spreading from the depths of the oceans to the layers of the atmosphere.
