Answer:
true
Explanation:
convection currents occur when a heated fluid expands, becoming less dense, and rises. The fluid then cools and contracts, becoming more dense, and sinks
heat go up, cold go down. they cycle.
Answer:
<em>First</em>, photosynthesis converts carbon dioxide and water into oxygen and glucose.
<em>Then</em>, glucose is used as food by the plant and oxygen is a by-product.
<em>Next</em>, Cellular respiration converts oxygen and glucose into water and carbon dioxide.
<em>Last</em>, water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
hope dis helps ^-^
I think it’s C but not precisely sure about it
The three structures that are most likely found in all fish are: blood, fins, and gills.
Answer:
second)some of the energy disperses as heat
Explanation:
This second law of thermodynamics states that in the course of conversion of energy from one form to another in an organisms,this can not be 100% efficient ( there is constant increase in entropy of the systems in the organism)as some of the energy is dissipated as heat in the course of conversion.
Thus in a food chain as energy is been converted from one trophic level( primary consumer) to another( secondary consumer) these organism makes use of the energy to do biologic work.Therefore as this is passed to other organism in the tropic levels not all the initial energy will be available ,as some has been lost during biology work,respiration , excretion ,movements and locomotion. in the subsequent organisms.
Thus the entropy of the organisms involved increases as energy is been transmitted from one trophic level to another which leads to heat dispassion.
