Answer;
The two processes used by producers to obtain energy are photosynthesis and chemosynthesis.
Explanation;
Producers are those organisms that can make their own energy in an ecosystem using biochemical processes. These biochemical processes are photosynthesis and chemosynthesis.
Photosynthesis involves use of energy from the sunlight together with water and oxygen to make simple sugars. The process converts solar energy to chemical energy (simple sugars).
Chemosynthesis involves use of chemicals as the energy source, rather than sunlight , to make simple sugars such as glucose.
Glucose from both processes is then used for respiration to generate energy or stored in form of starch.
the answer is negative marked as brianlest??!!!
Answer:
Due to their hole size.
Explanation:
Some molecules can pass directly through the phospholipid bilayer because of their small size which can easily pass through the small holes of phospholipid bilayer, while those that are too large or too charged need to pass through a membrane protein because membrane protein has a large holes through which large molecules can easily pass through the semi-permeable membrane of the cell by active or passive transport.
Well for one, we used coal for electricity, water for steam engines when they were much in use, natural fossil feuls for our gasoline and oil, and we use earths oxygen/nitrogen gasses to breathe and sadly we are polluting it at a fast rate
