True or false? To make up for the loss of energy when solar energy is used by primary producers and then transferred up the food chain, a continuous supply of solar energy to the ecosystem is required.
Answer: Energy can not be lost, rather it can be converted into other forms of energy , so false.
Explanation:
To make up for the loss of energy when solar energy is used by primary producers and then transferred up the food chain, a continuous supply of solar energy to the ecosystem is not required. Thus, the given statement is false.
What is energy cycle in an ecosystem?The energy flow in the ecosystem is important to maintain an ecological balance in the ecosystem. The producers in a food chain synthesize food by the process of photosynthesis. A part of this energy is stored within the plant species.
The energy cycle in an ecosystem is based on the flow of energy through the ecosystem. The energy from sunlight is converted by the plants them into the growing new plant materials including the flowers, fruits, branches, trunks, and roots of the plants. Since, the plants can grow by converting solar energy directly into their tissues.

Explain how your model demonstrated energy transformation from thermal energy to mechanical energy during a volcanic eruption.
(I mixed warm water, vinegar, and baking soda)
Answer:
Well to begin with, the thermal energy is mostly provided by the energy contained in warm water, when mixed with the other two components the chemical units are modified to form a composite solution that will result in an energy release, this energy release generate a movement, which in this case is the eruptive movement simulating the eruption of a volcano.
Explanation:
By mixing the vinegar (which is an acid) with the baking soda (which is a base), they react and transform into water, sodium acetate (a salt), and carbon dioxide (a gas). Carbon dioxide (CO2) is the gas that causes bubbles to form from the eruption of the volcano and balloons to swell.

Adaptations affect a species by making the species more likely to survive. Thus, the correct option is B.
What is Species?Species may be defined as a cluster of organisms that can reproduce with one another in nature and produce fertile offspring.
Adaptations may be defined as the process through which an organism makes itself better to be suited to the natural environment.
It increases the chances of a particular species surviving and reproducing in a natural environment.
Therefore, adaptations affect a species by making the species more likely to survive. Thus, the correct option is B.

Answer:
Smartphones and data centres are damaging to the environment and will have the biggest carbon footprint in the tech industry by 2040, researchers have found. ... While these phones consume little energy to operate, 85% of their emissions impact comes from production, the researchers said.
Explanation:
Answer:
Making a phone accounts for 85–95 percent of its annual carbon footprint because manufacturing its electronics and mining the metals that go into them is energy-intensive. The analysis showed that smartphone emissions will go up from 17 to 125 megatons of carbon dioxide equivalent between 2010 and 2020.
