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>
<h3>Answer:</h3>
Jean has a sample of a liquid. If she changes the liquid's phase by <u>Evaporating</u> it, the molecules will spread out, allowing the sample to expand and fill a container of any shape or volume.
<h3>Explanation:</h3>
Evaporation is a kind of condensation that happens on the surface of a liquid as it turns into the gas state before approaching its boiling point. The enclosing gas must not be immersed with the evaporating matter. Evaporation is a major element of the water cycle and is continually happening throughout the environment.
i think its D but i'm not 100% sure
Water
Soil
The sun
Atmospheric Gases
Temperature.
