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>
The evidence that paleobotanists look for that indicates the movement of plants from water to land is the possession of waxy cuticle to decrease evaporation from leaves.
<h3>What are some adaptations of plants on land compared to water?</h3>
Plants possess various adaptive features which enables them to survive on land or in water.
Plants that are found in water are known as aquatic plants. They possess features which enable them to get rid of excess water as well as to stay afloat on water. For example, their leaves are waxy to enable them remain afloat.
Plants found on land are terrestrial plants and possess features that enable them survive on land. They possess features which prevent excessive water loss such as waxy cuticle.
Therefore, the evidence that paleobotanists look for that indicates the movement of plants from water to land is the possession of waxy cuticle to decrease evaporation from leaves.
In conclusion, plants show adaptations as they moved from water to land.

Photsynthesis to make food
The main structural difference between LDL and HDL is their compositions. Approximately 50% of the weight of an LDL particle is cholesterol and only 25% is protein. High-density lipoprotein particles, on the other hand, consist of 20% percent cholesterol by weight and 50% protein.
“Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.”
