Question

food and water
organisms require food and water to survive. since there isnt always an endless amount of food and water, they are limiting factors.
suppose a bear must eat 10 fish a day to survive. the river nearby provides about 100 fish a day without harming the fish population. five bears could easily live in this area because they would only need 50 fish total. but if there were 15 bears they would not all survive because there would not be enough food. no matter how much shelter and water there was, the population would not get larger than 10 bears for any extended period of time.

1. how can food availability limit bear population growth?

food availability can limit bear population growth by....................................................

1. what would be limiting factors for plant growth?

the limiting factors would be....................................................

Explanation:

For question 3: The text gives an example of bears needing fish (food). When there's not enough food (like if too many bears exist), not all can survive. So food availability limits population as it determines how many individuals can be sustained.
For question 4: Based on general knowledge in biology (a sub - field of Natural Science), plants need sunlight for photosynthesis, water for various physiological processes, nutrients (like minerals from soil) for growth and development. If any of these are lacking, plant growth is limited.

Answer:

1. Food availability can limit bear population growth by determining the maximum number of bears that can be sustained. If there is not enough food (e.g., fish for bears), not all individuals in a larger population can survive.
2. The limiting factors would be sunlight (for photosynthesis), water (for physiological processes), and nutrients (like minerals from the soil).
