Which organisms have the greatest biomass?
Explanation: In general, the higher the trophic level (increasingly apex predators), the lower the biomass. Therefore, the lowest trophic level has the greatest biomass, and those are the producers. These include things like grass, trees, and flowers.
Which part of the food web contains the greatest biomass?
Which organism in the food web has the most energy?
Producers: Also known as autotrophs, these organisms make their own food through the process of photosynthesis. Producers make up the first trophic level, thus having the greatest overall biomass.
Which part of the food web contains the least biomass?
What is food web in ecosystem?
Food web is an important ecological concept. Basically, food web represents feeding relationships within a community (Smith and Smith 2009). In a detrital food chain, dead organic matter of plants and animals is broken down by decomposers, e.g., bacteria and fungi, and moves to detritivores and then carnivores.
Is a rabbit a tertiary consumer?

Is Moss a Gymnosperm?
There are four main groups of land plants: bryophytes, pteridophytes, gymnosperms, and angiosperms. The most common bryophytes are mosses. The pteridophytes include ferns. The gymnosperms include pines and other conifers.
Why is Moss Non-Vascular?
patens. Mosses are non-vascular plants with about 12,000 species classified in the Bryophyta. Unlike vascular plants, mosses lack xylem and absorb water and nutrients mainly through their leaves. Genome duplication seems to have contributed to the expanded gene number in Physcomitrella.
Which one is not a true moss?
Reindeer moss is a type of lichen found in the Arctic land. Whereas Bog moss is also called as peat moss and belongs to Bryophyta and follows key characteristics of the mosses such as alternation of generation and stores water due to the presence of cuticles. Thus, the correct answer is option B.
What is moss used for?
Sphagnum moss is used by the nursery industry as a plant growth medium. Moss is an excellent alternative to mulch since it absorbs water, prevents erosion and debris can be blown off easily because of its compact growth habit. It is also useful in mosquito control since it does not become stagnant, but purifies water.
Does Moss produce oxygen?
Like all live plants, aquatic mosses produce oxygen as a byproduct of photosynthesis which can help maintain ideal oxygen levels in your tank water.
What happens if you eat moss?
As with any wild edible, eating mosses and lichens is risky. While these growths rarely are fatal, they can give you a fierce stomach ache if not prepared properly. Be cautious to identify your food source.
Does Moss harm concrete?
Moss, a velvety green plant organism, grows on exterior concrete surfaces that are not exposed to sunlight and remain in a persistently moist state. While moss is not harmful to concrete, its presence on concrete patios and walkways can make them more slippery, causing a safety hazard.
