- If an organism requires something to perform a process, then increasing that something increases that organism's ability to perform that process
- An aquatic animal is a kind of organism
- Hence, if an aquatic animal requires something to perform a process, then increasing that something increases that aquatic animal's ability to perform that process

- If an aquatic animal requires something to perform a process, then increasing that something increases that aquatic animal's ability to perform that process
- An aquatic animal requires great amounts of water to thrive
- So, increasing the amount of water in an environment increases aquatic animals' ability to thrive in that environment

- Increasing the amount of water in an environment increases aquatic animals' ability to thrive in that environment
- If a species of animal is able to thrive in an environment, then the population of that animal will increase
- So, as water increases in an environment , the population of aquatic animals will increase

- As water increases in an environment , the population of aquatic animals will increase
- An otter is a kind of aquatic animal
- Hence, as water increases in an environment, the population of otters will increase

- When a body of water receives more water than it can hold , a flood occurs
- As the amount of rainfall increases in an area , the amount of available water in that area will increase
- Hence, heavy rains cause flooding

- Heavy rains cause flooding
- Floods are a source of water
- Therefore, flooding increases the amount of water in an environment

- As water increases in an environment, the population of otters will increase
- Flooding increases the amount of water in an environment
- Therefore, a flood will cause the population of otters to increase in an environment

Hence, a flood will cause the population of otters to increase in an environment
