Question

Total organic matter present in the ecosystem is called
A. Biomass
B. Biome
C. Litter
D. Food

Answer 1

Hint: Organic matter is abundant in the ecosystem and is circulated by soil microbial communities via decomposition processes. It may pass into soil and water after decaying and reacting. Organic matter provides nutrients for living creatures.

Complete Answer:
- The ecosystem is a population or collection of living organisms that live in and communicate with each other in a particular climate. These biotic and abiotic components are interlinked by food cycles and energy flows.
- Biomass is organic, meaning that it is composed of food that comes from living things, such as plants and animals. Plants, wood and waste are the most important biomass materials used for heating. This is classified as biomass feedstocks. Biomass energy may also be a non-renewable source of energy.
- A biome is a group of plants and animals that have similar characteristics for the ecosystem in which they live. They can be found on a variety of continents. Biomes are distinct biological communities that have been developed in response to a common physical environment.
- Litter consists of waste materials which have been disposed of incorrectly, without permission, at an unsuitable venue. Huge and hazardous waste products such as tyres, electrical equipment, electronics, batteries and large commercial containers are often discarded in remote areas, such as national parks and other public lands.
- Food is any material used to supply the body with dietary help. Food is typical of plant, animal or fungal origin and contains essential nutrients such as sugars, fats, proteins, vitamins or minerals.

So, the correct answer is Option A, Biomass.

Note: Today, we use four types of biomass, including wood, solid waste, biogas and alcohol. Most of the biomass used today is home-grown energy. Wood accounts for approximately 44% of biomass energy. Examples of biomass include timber, grass, chicken litter and energy crops such as willow and poplar.
