Natural selection leads to evolution because the strongest survive and pass on their genes
Answer: An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes.

Answer:
The transfer of energy through empty space is called convection.
Explanation:
One of the fundamental laws of the universe is the conservation of energy. Energy can't be created and it can't be destroyed. Convection can be the process by which heat is transferred . Temperature is known as the basic principle of heat transfer. The amount that how much of thermal energy can be available is determined by the temperature, and the heat flow represents movement of thermal energy.
