○ examples: ______________
● although we may not think of them as hunters, ______________ are
predators to ____________ (____________)
● predator-prey relationships like these account for ______________ of the
____________ transfers in a food ____________.
predator- prey relationships
● a predator-prey relationship tends to:
○ as the ____________ population __________, there is ____________ food for
____________. after a slight lag, the ____________ population
______________ as well.
○ as the number of predators ____________, ____________ prey are captured. as a
result, the ____________ population starts to ____________.

Explanation:

Predation involves a predator consuming prey. As prey population increases, there is more food for predators, causing predator population to rise after a lag. When more predators are present, more prey are captured, leading to a decrease in prey population, which then causes the predator population to decline due to less food. This is a common ecological interaction.

Answer:

• Predator - does the consuming. Examples: Lion (consumes zebras)
• Prey - gets consumed. Examples: Zebra (is consumed by lions)
• Although we may not think of them as hunters, ladybugs are predators to aphids.
• Predator - Prey relationships like these account for energy transfers in a food web.
• As the prey population increases, there is more food for the predator population. After a slight lag, the predator population increases as well.
• As the number of predators increases, more prey are captured. As a result, the prey population starts to decrease.
