•CALCULATE THE ENERGY AVAILABLE AT EACH LEVEL USING THE 10% RULE•
• PRODUCER .1%
• HERBIVORE 1%
• OMNIVORE 10%
• CARNIVORE 100%

THE ENERGY AVAILABLE AT EACH LEVEL USING THE 10% RULE :

Plants = 100 Kcal

herbivores = 10 Kcal

omnivores = 1 Kcal

carnivore= 0.1 Kcal

Explanation:

With the upward movement in a trophic level the energy transfer decreases. Only 10 % of the energy is transferred to the other trophic level, the majority of energy is dissipated as heat. This is the energy which is used for metabolic processes as respiration, excretion, digestion and in the process of reproduction.

Plants are the producers and initiators of the energy pyramid. It is from here the energy gets transferred to other levels based on the eating habits.

Herbivores are the primary consumers. Omnivores consuming herbivores and plants are secondary consumers and the carnivores are tertiary consumers.

Using 10 % rule of energy transfer

Plants = 100 % energy will transfer 10 % energy to herbivores

plants 100%

herbivores = 10 Kcal

omnivores = 1 Kcal

carnivore= 0.1 Kcal

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
