Biomass refers to
A
Chemical Energy
B
Light Energy
C
Rank in the feeding heirarchy
D
Amount of living tissue in an ecosystem
Explanation: 

Detailed explanation-1: -Biomass refers to the mass of living organisms, including plants, animals, and microorganisms, or, from a biochemical perspective, cellulose, lignin, sugars, fats, and proteins.

Detailed explanation-2: -Biomass in an ecosystem is the mass or weight of living tissue, which is commonly subdivided into five fundamental trophic levels forming the basic food chain: 1. producers, which are green photosynthesizing plants 2. herbivores, which eat producers 3. predators, which eat herbivores 4.

Detailed explanation-3: -Biomass is organic, meaning it is made of material that comes from living organisms, such as plants and animals. The most common biomass materials used for energy are plants, wood, and waste. These are called biomass feedstocks. Biomass energy can also be a non-renewable energy source.

Detailed explanation-4: -Total biomass is found by summing the dry mass biomass of all individuals in a given land area and then reported by naming the area of concern, e.g. biomass per plot, ecosystem, biome, classroom. To be able to compare biomass in different locations, scientists standardize biomass per unit of area.

Detailed explanation-5: -Each trophic level has a certain mass of living material at a particular time called as the standing crop. The standing crop is measured as the mass of living organism (biomass) or the number in a unit area .
