Answer:
Not all the energy is passed from one level of the food chain to the next. About 90 per cent of energy may be lost as heat (released during respiration), through movement, or in materials that the consumer does not digest. The energy stored in undigested materials can be transferred to decomposers.

Why did the students leave the amylase and starch solutions in the water bath for five minutes in step 3
Answer:
Each enzyme functions at an optimum temperature. Below the optimum temperature, the enzyme's function slows, and will eventually become inactive. Above the optimal temperature, the enzyme's activity will slow. Too far above the optimum temperature and the enzyme becomes denatured (its shape changes) and it can no longer function. Amylase is the enzyme that breaks starch (amylose) down into maltose. The amylase and the starch were placed in the water bath to allow the reaction to occur at amylase's optimum temperature of 37 C.

4. Describe the large-scale change that occurred at Coldwater Creek after the eruption. What effect would this have had on the local ecosystem?
The gases and dust that the volcanic eruption releases changes the climate because most particles erupted shade incoming solar radiation causing the global climate to cool down.
What are the different ways to recover grassland ecosystem after volcanic revolution?The volcanic eruption destroys a grassland ecosystem. They burns the place and the plants. The dusts cover up the leaves and the heat kills the seeds and spores of the plants. The recovery isn’t easy and fast.
As the volcano lava cools and subsides, the new vegetation starts to grow.
The seeds are brought by the wind, birds and other animals that are spread over the landform. The rain provides the necessary water for germination. Volcano supplies the necessary minerals that are very good for plant growth.Thus, most particles erupted shade incoming solar radiation causing the global climate to cool down.

The three gases that are part of Earth’s cycles in both the atmosphere and biosphere are:
oxygen- nitrogen- carbon dioxideExplain your answer?
The oxygen, nitrogen, and carbon dioxide are the three gasses that are constantly moving through the atmosphere and biosphere in their own respective cycles.
The oxygen is used by the animals for breathing, but it is also released as a byproduct by the producers. The nitrogen is used as a food source for the producers, as well as the carbon dioxide which is crucial for the process of photosynthesis.
Thus, Part of them is released through decomposition, part by releasing them in the atmosphere or in the soil.

What should scientists do when a new discovery is made that goes against a long-accepted theory?
He should analyze and compare his findings with findings already accepted within the scientific community.
What is theory?A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.
A theory not only explains known facts as it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable. New evidence should be compatible with a theory. If it isn't, the theory is refined or rejected. The longer the central elements of a theory hold the more observations it predicts, the more tests it passes, the more facts it explains the stronger the theory.
