In the early 1900s Germany geologist alfred wegener began to question how the structure of Earth formed over time he proposed the theory of continental drift to suggest that all continents were once connected and have drifted to their current location over time. What was the main reason that wegener theory received a lot of radical from the scientific community

He did not give a method on how the continents moved

Explanation:

In 1912, Alfred Wegener proposed the idea that the continents are slowly drifting around the Earth. This hypothesis was known as the continental drift. Wegener proposed that the Earth rotation might have been the cause for which the continents move to separate from each other. However, nowadays it is well-known that continents are landmasses localized on tectonic plates that move and interact with each other (and it is referred to as plate tectonics).

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
