Answer:
Autotrophs are the plants which prepare their food by photosynthesis.
Explanation:
If the side of the triangle is ' S ', then . . .
-- Base of the triangle = S
-- Height of the triangle = 1/2 S √3
-- Area = 1/2 (base) (height) = (S² √3) / 4
-- Perimeter = 3 S
Area / Perimeter (numerical) = [ (S² √3) / 4 ] / 3 S
That ugly thing becomes <em>S √3 / 12 </em> .
Answer mad cow disease
Explanation:
100% case mortality rate
Humans may acquire the disorder by eating diseased meat products. When it comes from cattle, the disorder is called Creutzfeldt-Jakob disease and ultimately leads to dementia and death. The condition is rare.

Treatment focuses on keeping the person as comfortable as possible.
Answer:
In biomass pyramid living matter is present at all the trophic level in the ecosystem.
Explanation:
There are three ecological pyramids that are the pyramid of biomass, the pyramid of energy, and the pyramid of numbers.
Pyramids of biomass represent the total living matter present at each of the trophic levels in the ecosystem. It shows how much biomass of lower trophic levels is required to support the biomass of successive trophic levels.
The pyramid of biomass can be straight or inverted. In straight pyramid, larger biomass of lower trophic level supports smaller biomass of upper trophic level and vice-versa occurs with an inverted biomass pyramid. The pyramid of the number shows the number of the organism at each trophic level.
