Only 10% of the energy consumed by an organism is available to be transferred to another trophic level due to the laws of thermodynamics and the inefficiency of energy transfer.
Only 10% of the energy consumed by an organism is available to be transferred to another trophic level due to the laws of thermodynamics and the inefficiency of energy transfer. This is known as the 10% rule.
The 10% rule states that energy is lost as heat during the process of respiration and metabolic activities, and only a fraction of the remaining energy is converted into biomass that is available as food for the next trophic level.
For example, if a primary producer (such as a plant) has 1,000 units of energy, only 100 units are passed on to the primary consumer (herbivore), and only 10 units are transferred to the secondary consumer (carnivore) in the next trophic level.
a. True
b. False
Answer:
b. False
Explanation:
The spiral ganglion, formed from the primitive otocyst, is located on the cochlea's modulus (axis) and is made up of approximately 35,000 neurons in man. These bipolar neurons are of two types: type I and type II. Its peripheral extensions (dendrites) end in the spiral organ, in contact with the hair cells of which they receive information. Its central extension (axon) ends at the cochlear nuclei of the brainstem.
A population of raccoons lives in a forested area with lots of trees. The raccoons eat insects, eggs, berries, nuts, and small animals such as
rodents and frogs. One of the main predators of the raccoons are coyotes, which also prey on rabbits.
Identify whether the changes to the ecosystem are more likely to increase or decrease the population of raccoons.
Large parts of the forest
are cut down for wood.
Pollution from a nearby farm
decreases the population
of insects in the forest.
Additional rain increases
the population of plants
in the forest
More permits to hunt
coyotes are approved.
A disease decreases
the population of rabbits
in the forest.
Frogs in a pond near
the forest experience
a population surge.
Increases Population
Decreases Population
Answer:
Explanation:
A
Explanation:
Plants in forest are not supplied with fertilizer by human beings ,yet they get mineral and salt from the dead decaying body of plants and animal found in the forest .Animal die in forest get converted into humus by bacteria and other animals .Sources of energy is transferred from one life to other by different means in this way plants in forest get plant and mineral.
b. phagotrophs
c. osmotrophs
d. saprozoic feeders
Answer:
The correct answer will be option-B.
Explanation:
Protist is the group of the organism which is eukaryotes but nither considered true animals, fungi and plants.
Their mode of nutrition is either osmotrophic or phagotrophic. The phagotrophic feeds on the macroparticles like organic particles by surrounding the particle and swallowing it through phagocytosis. The ingested particle gets digested inside the body pf the organism. The phagotrophic organisms are like amoeba and dinoflagellates.
Thus, Option-B is the correct answer.
Answer:
Prometaphase (late prophase)
Explanation:
Mitosis is the kind of cell division in which two genetically identical copies of a cell is formed from a cell. Mitosis comprises of stages which include prophase, metaphase, anaphase and telophase. Each phase is characterized by specific occurrences that all work together to achieve the main goal of forming two daughter cells.
According to this question, PROPHASE stage is the stage characterized by the condensation of chromatids into chromosomes, the disappearance of nucleolus and BREAKDOWN of NUCLEAR MEMBRANE.
A. Warm air continuously leaves the poles and moves toward the
oceans.
B. Warm air rises and cool air sinks, forming a convection current
C. Warm air moves away from the equator toward cooler regions.
D. Warm air flows from the northern hemisphere to the southern
hemisphere.
Explanation:
I think it is b because when warm air rises it always affects the earths weather pattetn
