Based on the description of events, being that the lizard population appears to increase as soon as the snake population decreases, it appears that the snakes prey on the lizards. This suggests that the snake is a keystone species. A keystone species is one that has a dramatic effect on maintaining the balance of an ecosystem. As soon as the snake population decreases, major changes occur to the ecosystem, such as the lizard population increasing.
Therefore, the answer is D: <span>The snake is a keystone species in the ecosystem.</span>
Explanation:
When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale

Adenosine triphosphate (ATP) is a cell's energy currency. All of the following statements about ATP are true, except ATP is used to lower activation energy in enzymatic reactions.
- A) ATP is used to lower the activation energy in enzymatic reactions.
<h3>How does ATP affect enzyme activity?</h3>
Enzymes allow chemical reactions to proceed with activation energy provided by the catabolism of ATP. When cells convert glucose and oxygen into carbon dioxide and water, they use 2 molecules of ATP as activation energy and gain 36 to 38 molecules of ATP in return. Without enzymes, this would not be possible.
