Answer:
The answer to this question is 60 KJ.
Step-by-step explanation:
First, we will understand what a food chain is, and then we will understand the ten percent rule of the food chain which eventually will help us solve this problem.
A food chain refers to the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism. The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain.
The food chain also explains the feeding pattern or relationship between living organisms. The trophic level refers to the sequential stages in a food chain, starting with producers at the bottom, followed by primary, secondary, and tertiary consumers. Every level in a food chain is known as a trophic level.
The food chain consists of four major parts, namely:
The Sun: The sun is the initial source of energy, which provides energy for everything on the planet.
Producers: The producers in a food chain include all autotrophs such as phytoplankton, cyanobacteria, algae, and green plants. This is the first stage in a food chain. The producers make up the first level of a food chain. The producers utilize the energy from the sun to make food. Producers are also known as autotrophs as they make their food. Producers are any plant or other organisms that produce their nutrients through photosynthesis.
Consumers: Consumers are all organisms that are dependent on plants or other organisms for food. This is the largest part of a food web, as it contains almost all living organisms. It includes herbivores which are animals that eat plants, carnivores which are animals that eat other animals, parasites that live on other organisms by harming them, and lastly scavengers, which are animals that eat dead animals’ carcasses.
Here, herbivores are known as primary consumers and carnivores are secondary consumers. The second trophic level includes organisms that eat producers. Therefore, primary consumers or herbivores are organisms in the second trophic level.
Decomposers: Decomposers are organisms that get energy from dead or waste organic material. This is the last stage in a food chain. Decomposers are an integral part of a food chain, as they convert organic waste materials into inorganic materials, which enriches the soil or land with nutrients.
Decomposers complete a life cycle. They help in recycling the nutrients as they provide nutrients to soil or oceans, that can be utilized by autotrophs or producers. Thus, starting a whole new food chain.
The 10 percent rule.
10% law. When organisms are consumed, approximately 10% of the energy in the food is fixed into their flesh and is available for the next trophic level (carnivores or omnivores). When a carnivore or an omnivore in turn consumes that animal, only about 10% of energy is fixed in its flesh for the higher level.
