Select all that apply. Acidity Animals Humidity Oxygen Sunlight Bacteria Fungi

Answer 1

The true statements regarding biomes are:

• Biomes have defined boundaries call biome gradients
• Biomes have no specifically defined boundaries

Step-by-step explanation:

Biomes are broad categories of ecosystems defined by the communities of plants and animals they contain, and by their characteristic physical environments such as soil type, climate, and geography. Some key points:

• There are many biomes on Earth, with estimates ranging from 20 to over 120 depending on classification schemes. There is no definitive number of 6 biomes.
• Biomes do have conceptual boundaries defined by changes in dominant vegetation and climate. However, the boundaries between biomes are gradual zones called ecotones or biome gradients, rather than sharp lines.

-Biomes are not at the top of the hierarchy of life. They sit between larger scales like biogeographic regions and smaller scales like ecosystems and habitats.

For the second question, the abiotic components listed are:

• Acidity
• Humidity
• Oxygen
• Sunlight

Abiotic components refer to non-living physical and chemical factors that influence organisms and ecosystems. They include things like soil, climate, sunlight, and water. Animals, bacteria and fungi are biotic components - living parts of an ecosystem.

Answer 2

biomes have no specific boundaries
