Answer:
b. Net production is always less than gross production.
Explanation:
The main production i.e. done in ecology would do the production in the organic compounds with the help of photosynthesis. The gross production is the value i.e. generation of organic compounds by producers while the net production is the value of organic compounds i.e stored by producers. It should be lower than the gross production as the plants are not able to store large number of organic compounds than they generated

C. The difference in density between land and water
D. The difference in specific heat capacity between land and water
Need a 100% correct answer please
Answer:
During the day, the sun heats up both the ocean surface and the land. ... The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse.

Predict: Why aren't all organisms made of just one cell?
Why do cells divide, instead of simply growing larger?
The living beings that are comprised of more than one sort of cell are known as Multicellular Organisms.
Why organisms are made up of cells?These organelles are liable for an assortment of cell capacities, for example, acquiring supplements, creating energy, and making proteins. Unicellular living beings are comprised of just a single cell that completes each of the capacities required by the organic entity, while multicellular creatures utilize various cells to work.
Cells divide because:
Cells need to separate for your body to develop and for body tissue, for example, skin to restore itself ceaselessly.

If a dormant volcano starts to release gases and small earthquakes are recorded, what could this mean?
Answer: It means that its showing some volcanic activity that could lead into an eruption.
Explanation: Dormant volcanoes can show activity/signs that is could erupt. Gases, small earthquakes, loud explosions are signs of an eruption is going to occur. If a dormant volcano hasn't showed any activity for 2,000 years, its considered to be dead or extinct.
It indicates that there is some volcanic activity, which could lead to an eruption.
What is dormant volcano?Dormant volcanoes are those that have not erupted in a long time but are expected to do so in the future. Mount Kilimanjaro in Tanzania, Africa, and Mount Fuji in Japan are examples of dormant volcanoes.
Volcanoes become dormant when magma from the Earth's mantle can no longer reach them. Mount Rainier and Mount Fuji are examples of dormant volcanoes that are "sleeping" but may awaken in the future.
Dormant volcanoes can exhibit activity/signs that they are about to erupt. Gases, small earthquakes, and loud explosions are all indicators that an eruption is about to occur.
If a dormant volcano hasn't erupted in 2,000 years, it's considered dead or extinct.
Thus, this way, it indicates that it could lead to eruption.
