Answer:
Most plants are auto trophic able to use sunlight as their primary source of energy,in a process called photosynthesis.This process enables them to turn carbon dioxide from the air into food,The carbon and oxygen which they need in order to build up their bodies ultimately comes from this carbon dioxide.
All animals are heterotrophs, which means that they cannot make their own food as plants do. Rather, animals must obtain the energy, carbon, hydrogen, oxygen, nitrogen, and minerals they need by consuming other living things. Animals are also animate, which means that they are capable of movement.
Burning charcoal, heat from an electric heater, fire or a radiator emitting warmth those are just a few
4 Because animals that raise their young in packs is a cooperative task
Answer: B. Producers
Explanation:
A food chain is basically a sequence of transfer of food and energy when one organism is consumed by other organism in an ecosystem. In an energy pyramid linked with food chain the producers are present in the lowermost base level trophic level. These organisms exhibit the highest amount of energy as compared to other trophic levels. As these organisms are capable of producing their own food by process of photosynthesis by obtaining the energy from sunlight or by chemosynthesis. This energy decreases in subsequent trophic levels when producers are consumed by consumers.
Connective tissue but there are different types; loose connective tissue, dense connective tissue, etc.
