Answer:
It depends on the temperature of the cookie sheet.
Explanation:
If the temperature of a cookie sheet is higher than the container used by Kennya, then the evaporation of water is faster because the water molecules quickly gains the kinetic energy that helps them in the evaporation while on the other hand, if the cookie sheet is not hot enough as compared to the container, the evaporation rate is slower but if both have same temperature so the evaporation is remain the same.
Species change over time. -The mechanism that produces the change is natural selection: the differential survival and reproduction of individuals based on variation in their traits. Natural selection acts on individuals but individuals do not evolve; their descendants do.
Oxygen is an abiotic factor that is beneficial by-product of primary production.
<u>Explanation:</u>
The non living parts of an ecosystem that mainly affects the living organisms in it are called as an abiotic factor. These can include soil, temperature, water, oxygen and sunlight. The major energy source in earth is Oxygen which is abiotic factor.
It is very essential for the photosynthesis process to take place. Here, the plants converts water and carbon dioxide into oxygen and sugar. This becomes food for plants.
