Question

directions: use the pictures to answer the questions about each cycle in nature. 1. how does the water cycle help plants and animals? 2. how do plants and animals obtain the nitrogen they need? 3. how do plants and animals help maintain a balance of carbon dioxide in the atmosphere?

Explanation:

1. The water cycle provides water for drinking, growth, and survival to plants and animals. It also helps in maintaining habitats like rivers, lakes, and wetlands.
2. Plants obtain nitrogen through the soil, where nitrogen - fixing bacteria convert atmospheric nitrogen into a usable form. Animals get nitrogen by eating plants or other animals that have consumed nitrogen - containing plants.
3. Plants absorb carbon dioxide during photosynthesis, reducing its amount in the atmosphere. Animals release carbon dioxide during respiration. Decomposition of dead plants and animals also recycles carbon back into the atmosphere, maintaining a balance.

Answer:

1. The water cycle provides water for drinking, growth, and maintains habitats for plants and animals.
2. Plants get nitrogen from the soil (via nitrogen - fixing bacteria) and animals get it by eating plants or other animals.
3. Plants absorb carbon dioxide during photosynthesis and animals release it during respiration; decomposition also recycles carbon, maintaining balance.
