When energy passes from one trophic level to the next, I would guess that the two factors which decrease the total amount of energy from being passed up are:
1. An organism does not assimilate all the energy of food consumed. Within a consumer, digestion and assimilation of energy is not 100% efficient: some of the energy is lost.
2. A large proportion of energy assimilated by a producer and consumer is lost through respiration, i.e., day-to-day maintenance of metabolic processes.
Answer:
No
Explanation:
This is because oxygen will not be available for breathing and energy will not be released for cellular activities because photosynthesizing organisms have chlorophyll and trap light energy ffrom sunlight , using carbondioxide and water to produce glucose and oxygen. Oxygen is the by product which is the gas that is inhaled by living organisms during respiration and also break glucose to release ATP. Therefore without these organisms, respiration will be difficult.
Answer:
Plants and animals
Explanation:
Cellular respiration occurs in the mitochondria, known as the "powerhouse of the cell." Since both plants and animals require energy and have mitochondrion, they will both perform cellular respiration.
A single motor neuron together with all the skeletal muscle fibers it innervates is called a motor unit.
- Motor neurons are more than just relays for the motor commands sent down the hierarchy from higher levels. They themselves are parts of intricate circuits that carry out extensive information processing.
- Due to their highly branching, intricate dendritic trees, motor neurons are able to integrate inputs from several other neurons and generate accurate outputs.
- A single motor neuron, and nothing else, innervates each and every muscle fiber (make sure you understand the difference between a muscle and a muscle fiber). However, several muscle fibers can be innervated by a single motor neuron.
- A motor unit is the aggregate of a single motor neuron and all of the muscle fibers that it innervates. The innervation ratio refers to how many fibers a motor unit innervates.
