Organisms that eat cows obtain less energy from the cows than the cows obtain from the plants they eat, because the cows...

• store all of their energy in milk.

• use energy for life processes and loses it to heat.

• pass most of their energy to their offspring.

The food web below shows the relationships between native organisms in an ecosystem. A nonnative predator that feeds only on hawks is introduced to the ecosystem. How is the new predator most likely to affect the ecosystem?

• Seed-bearing plants will become more abundant.

• The grasshopper population will decrease.

• The snake and the chipmunk populations will decrease.

• The hawk population will decrease and the snake population will increase.

The Iberian Lynx is a large cat that is native to Spain and Portugal. Over the last few decades, the lynxes main food source, rabbits, have contracted a deadly disease. How would this most likely affect the population of the lynx?

• The lynx population would increase because they would become vegan

• The lynx population would remain the same because they would adapt to eating other food.

• The lynx population would increase because they would produce more offspring to make up the difference.

• The lynx population would decrease since they will not have access to as much food.

Which of these statements is NOT true?
