The autotrophs are the primary producer in the food chain and they are the ones who initiate the food chain. They produce food by using sunlight or sometimes chemical energy or reactions. They primarily use carbon dioxide, sunlight and water to form sugars or carbohydrates which become their energy source. They use the process of photosynthesis or chemosynthesis to generate food. Examples of autotrophs are green plants, green algae, bacteria.
Heterotrophs cannot make their food via sunlight or other inorganic sources and hence are dependent on the autotrophs or other animals. The heterotrophs have been ranked as secondary and tertiary consumers and cannot be producers. They consume the organic products made by autotrophs to obtain energy for various metabolic and biological activities. The heterotrophs can be herbivore, carnivore, fungi, parasitic plants.
Some are photo-hetrotrophs, who use light as energy but cannot use carbon dioxide as the carbon source since they cannot fix the carbon like autotrophs.
Proteins perform numerous functions in the cell membrane, one of which is to regulate the movement of materials, atoms of elements and other ions as they are entering and exiting the cell. These proteins that play this significant role, would be classified as transmembrane proteins, which are specific kind of intergral proteins.
Its Unipotent !! C!! the word itself describes if you try to understand!!
The answer should be Environmental Protection Agency, because its the agency US federal government into mission of protecting environmental health or human health
Hope this helps.
In photosynthesis, carbon dioxide is reduced. This reduction occurs during the Calvin cycle. The energy for the reduction is gained from Light reaction.
<u>Explanation:</u>
The pigment called Chloroplasts that are present in plants helps them in the conversion of light energy into chemical energy. This pigment contains electrons has higher energy that will be transported in the photosynthesis p[process.
The main source of this process to take place is energy that is obtained from sun. Chlorphylls abosrb the solar energy.The electrons in the chloroplast produces NADPH and ATP. This process is called as the light reactions as the main source of this reaction is light.
