Answer:
Because they lose most of the energy as heat when they perform metabolic activities
Explanation:
Cells of all living organisms require energy in form of ATP to perform their cellular functions. In an ecosystem, organisms obtain this energy by feeding on one another. However, these energy transfer starts from organisms capable of using sunlight called PRODUCERS e.g plants.
Herbivores, which are PRIMARY CONSUMERS get their energy by feeding on these plants. However, according to the PYRAMID OF ENERGY, which represents the flow of energy in an ecosystem, only a few portion of the energy (about 10%) derived by plants from the sun gets transferred to herbivores. This is because most of the energy (about 90%) is lost as heat when the plants undergo metabolic activities.
The answer is; A
All living organisms seek energy to maintain life, humans included. This begins from a society that depends on wood and paraffin for energy to those that depend on electricity. When energy is in plentiful, then individuals in the population will not compete and fight for the resource. The price of the resource will also be affordable to the whole population. Therefore, people will be well settled to focus their energies on developing their societies through various economic activities.
Answer:
Option A, because enzymes denature at 40 degrees Celsius, and when it denatures the active side changes it shape so the substrate won't be able to fit into it.
Answer: Wrist
Explanation: The wrist connects the hand to the forearm. It consists of the distal ends of the radius and ulna bones, eight carpal bones, and the proximal ends of five metacarpal bones. This arrangement of bones allows for a wide range of movement.
