In dry years the biomass of producers is significantly decreased what would the effect be on a rodent population

The rodents like rats will be highly affected by the decline in the number of the producers during the dry spell. The rodents consume the grasses and other small insects like the grasshoppers and beetles that live on them. When the producers die, the amount of food available for the rodents goes down. This affects the survival as the food is required by the rodents for maintaining their body metabolism.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
