Answer:
Abiotic factors such as latitude and temperature can impact biotic aspects of food web structure like the number of species, the number of links, as well as the proportion of basal or top species. These biotics factors can in turn influence network-structural aspects like connectance, omnivory levels or trophic level. In this way, plants make, or produce, the beginnings of most of the food energy on Earth. This is why plants are called producers. They use some of the food energy to carry out their own functions, and store the rest of the energy in their leaves, stems, roots and other parts.

Answer: 25 joules 
Explanation:
Recall that kinetic energy is the energy possessed by a moving object.
So, kinetic energy = 1/2 X Mass X Velocity^2
Mass = 0.5kg
Velocity = 10m/s^2
= 1/2 x 0.5kg x 10^2
= 0.5 x 0.5 x 100
= 25 Joules
Thus, the kinetic energy of the moving ball is 25 joules
