Answer: Forest ecosystem have the maximum biomass, because it includes organisms of all tropic levels as compared to pond, lake or grassland ecosystem.
Why is the biomass of an ecosystem always greatest in the producers trophic level?
The first trophic level has the most biomass because it has the most energy according to the 10% rule.
Which trophic level contains the most biomass and why?
The tropic level that contains the greatest biomass in most ecosystems are producers. This occurs because producers get there energy from the sun, the sun is the most available resource and so there are the most at that level.
How does the amount of energy at the fourth trophic level compare to the amount of energy at the third trophic level immediately below it?
How does the amount of biomass at the fourth trophic level compare to the amount of biomass at the third trophic level immediately below it? Biomass at the fourth trophic level is approximately ten times smaller than biomass at the third torphic level.
Which of the following are biotic and which are abiotic factors?
Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organisms.
Which of the following are abiotic?
In biology, abiotic factors can include water, light, radiation, temperature, humidity, atmosphere, acidity, and soil.
Why do food chains and food web rarely have more than 4 and 5 trophic levels?
It is rare to find food chains that have more than four or five links because the loss of energy limits the length of food chains. At each trophic level, most of the energy is lost through biological processes such as respiration or finding food.
Why do most food chains only reach the fourth or fifth trophic level and no higher explain in terms of energy transfer and the 10% rule?
Food chains usually do not go beyond the fourth or fifth trophic level because energy transformations across trophic levels are never 100% efficient. Only 10% of the energy from one trophic level can pass onto the next trophic level. … The initial energy level in energy pyramids is called the “producers” energy level.
Why is the total biomass of secondary consumers lower than that of primary consumers?
The secondary consumers tend to be larger and fewer in number. This continues on, all the way up to the top of the food chain. About 50% of the energy (possibly as much as 90%) in food is lost at each trophic level when an organism is eaten, so it is less efficient to be a higher order consumer than a primary consumer.
Which organism would usually be in the fourth trophic level?
The fourth trophic level includes carnivores and omnivores which eat the animals that belong to the third level. Omnivores are animals that eat both plants and animals. Omnivores consume both primary producers and secondary consumers. Animals on this level are called tertiary consumers.
Who has occupied 4th trophic level?
-Fourth trophic level: Tertiary consumers come under the fourth trophic level of the food chain and are constituted by the top carnivores. So, the correct answer is ‘tertiary consumer. ‘ Note: -The first trophic level is primarily occupied by phytoplankton and plants (grass and trees).
