Energy is converted from one form to another.
Energy is created by the reaction.
Energy is used up by the chemical reaction.
The answer would be "B".
Answer;
-Since sunlight is where most of the energy in an ecosystem comes from, there is less sunlight deep in a lake meaning less organisms can survive.
Explanation;
-The reason why many plants don't live deep below a lake's surface is because lakes don't normally have chemical vents. Thus, making it hard for producers to find any sources of energy in the dark, deep waters of the lake.
-Since the deepest parts of a lake receive the least light, the ability of submerged macrophytes (plants larger than algae) to establish colonies is limited.
-The combination of low oxygen levels and low light limits the growth of plant communities at great depths; many plants living in very deep water have adaptations such as elongated stems or long structures so that at least some of the plant is in the water nearer the surface where it can photosynthesis.
Answer:
The correct answer is air enters the - Bronchi and smaller tubes called- Bronchioles.
Explanation:
In humans, the respiratory system includes specialized organs like nose, the pharynx (or throat), oral cavity, larynx, the trachea, the stem bronchi.
The process of respiration starts with inhaling the air through nose and mouth which travels down to the back of your throat and windpipe called trachea. The trachea then divides into air passage tubes called bronchi which ramify within the and is known as the bronchioles.
Thus, Bronchi and bronchioles are the correct answer.
b. carbon dioxide
c. nitrogen
d. hydrogen
