Two different types are pyramid are there, one inverted pyramid( shown in pond ecosystem, with mass of phytoplankton's-producers are lower; and than the heterotrophs- fish and insects) second one is upright one; in which the weight of producer is more than the consumers.

6. Energy transfer between organisms normally involves conservation of heat energy.
C. Energy is lost between trophic levels.
Answers
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.
B. it will go up sharply then go down sharply.

A. There is no diversity in the population,
O
B. The population is above carrying capacity.
O
C. There are enough resources for the birds.
O
D. There is nothing to cause genetic mutations.
Answers
The natural selection would not occur in this population because : ( C ) There are enough resources for the birds.
What is Natural selection
Natural selection is a process whereby populations of organisms living in an environment adapt and change due to selective reproduction of genes in its genotype. Natural selection is triggered by certain environmental factors. In the scenerio protrayed in the question there is an abundance of resources for the birds therefore natural selection will not occur.
Hence we can conclude that there are anough resources for the birds
