6. Energy transfer between organisms normally involves conservation of heat energy.
C. Energy is lost between trophic levels.
Energy is lost between trophic levels.
Answer: Option C
Explanation:
The source of energy for all organisms is the Sun. The Tropic levels exhibit the flow of energy in an ecosystem. The flow of energy is always in one direction. The energy level decreases crossing each trophic level as energy is lost in the form of heat.
Primary producers are the first in Trophic level, The Herbivores fall in the next level , the Carnivores form the next level and the decomposers are the last in the trophic level. The decomposers decompose all the living organisms and convert to nutrients that are available in the soil. The plants take up this nutrient and hence this is a cycle.
A.There is not enough of it in the air.
B.Nitrogen gas contains the element in an inert, unusable state.
C.They do use it directly from the atmosphere.
D.Plants and animals do not need nitrogen for their life processes.
b) metaphase)
c)anaphase
d) telophase
I need help!
Prophase: Replication of chromosomes and chromosome become visible x shapes.
Metaphase: Chromosomes align at the equator of the cell and spindle fibers attach to each sister chromatid.
Anaphase: Spindle fibers pull the sister chromatids away from each other to the opposite sides of the cell.
Telophase: New separate nuclear membranes form around the different sets of chromosomes and the chromosomes unwind, the spindle fibers start breaking down and and the cell begins to pinch together to separate into two new cells.
