Answer:
<u>Food chain as given below</u>
Explanation:
- A consumer is a living creature in the food chain that eats other consumers and maintains a balance in the food web. Primary producers are all green plants that prepare their food by their ability to utilize the sun's energy and convert that available raw energy into starch in their body by the process of photosynthesis.
- These Autotrophs take up the organic matter through their roots in the form xylem and phylum and giving oxygen in the air. They form the base of the food chain on which are dependent Herbivorous like sheep, goat, cow, etc.
- The secondary consumers are called the Carnivorous, like the lion, tiger, etc that feed on the bodies of herbivorous. Above this level is that of Omnivorous i.e both plant and animal eaters like the crow, man, and cat.
- As stated by the law of thermodynamics energy can neither be destroyed nor created but transforms itself. The flow of energy at each trophic level gets successively transferred to the next trophic level from primary to secondary tertiary and so on.
- Likewise, toxin concentration in trophic levels increased each level upwards and leads to biomagnification that is harmful to the entire food chain.
I attached a picture of the layers of the earth. They are the:
Crust (<em>which isn't really the interior</em>)
Mantle
Outer Core
Inner Core
The biosphere is all living things on earth
Researchers have developed a program that measures how many planet earths are needed to provide the resources humanity is using. this ecological yardstick is called ecological footprint
The Global Footprint Network promotes the ecological footprint as a way to assess how much nature is needed to sustain a given number of people or an economy. Through an ecological accounting system, it monitors this demand. The accounts compare the biologically productive areas used by people for consumption to the biologically productive areas available in a region or around the world (biocapacity, the productive area that can regenerate what people demand from nature).
