Question

Distinguish between;grazing food chain and detritus food chain. 2.upright and inverted pyramid. 3.food chain and food web 4.production and decomposition 5.litter and detritus 6.primary and secondary productivity

Answer 1

1.grazing food chain.
the chain begins with green plants.
energy for the food chain comes from Sun.
it consists of all macro organisms.
.detritus food chain.
the chain begins with .decomposers
energy for the food comes from the remains.
it consists of all sub soil organisms.
2.upright pyramid.
producers occupy a broad base.
consumers decrease in biomass or number.
pyramid of energy is always upright.
.inverted pyramid
producers occupy a narrow base.
consumers are more of terms in biomass or number.
they are inverted.
3.food chain follow a single path.
food web shows how animals are interconnected with others.
4.production
it is the process of synthesis of organic compounds from in organic matter using sunlight.
it traps energy.
it builds up biomass from inorganic nutrients.
.decomposition
it is the process of breaking down of substance into its constituent parts by decomposes.
it releases energy.
it releases inorganic nutrients from biomass.
5.litter
it is made of dried fallen matter.
it above the ground.
.detritus
it is made of remains of plant and animal
it is below the ground.
6.primary productivity
it is the rate at which radiant energy is captured by the producers for the synthesis of energy rich compounds in photosynthesis.
it is the fresh synthesis of organic matter from inorganic materials.
.secondary productivity.
it is the rate of storage at consumer level.the consumers use it and convert into various forms.
it is the synthesis of organic matter from organic material.
