Explanation:
A fixed pulley raises the load in a unidirectional manner... This therefore reduces the force required to raise that same load without the pulley.. It actually reduces the force required to raise objects
Answer:
The food chain that is described in the question is called Grazing food chain.
Explanation:
Grazing food chain is a type of food chain that contain producers at the lowest tropic level.The producers can manufacture their own food by photosynthesis process. Here grass act as producers.
The second topic level of grazing food chain contain primary consumers which consume producer. Here grasshopper eat grass,as a result grasshopper act as primary consumers or herbivores
The third tropic level of grazing food chain contain secondary consumers that feed on primary consumers. Here snake eats grasshopper,as a result snake act as secondary consumers or primary carnivores.
The highest tropic level of grazing food chain contain tertiary consumers or secondary carnivores.Hawk eats snake,as a result hawk act as Tertiary consumers or secondary carnivores.
Those organisms don't have chloroplasts in their cells which is required for photosynthesis to occur.
