what is the basis for energy in most ecosystems? how much energy is kept as you go up a energy pyramid or a food chain?why?​
zimovet [89]

Answer:

Primary producers—usually plants and other photosynthesizers—are the gateway for energy to enter food webs.

Productivity is the rate at which energy is added to the bodies of a group of organisms—such as primary producers—in the form of biomass.

Gross productivity is the overall rate of energy capture. Net productivity is lower, adjusted for energy used by organisms in respiration/metabolism.

Energy transfer between trophic levels is inefficient. Only about 10% of the net productivity of one level ends up as net productivity at the next level.

Ecological pyramids are visual representations of energy flow, biomass accumulation, and number of individuals at different trophic levels.

Introduction

Have you ever wondered what would happen if all the plants on Earth disappeared—along with other photosynthesizers, like algae and bacteria?

Well, our beautiful planet would definitely look barren and sad. We would also lose our main source of oxygen, that important stuff we breathe and rely on for metabolism. Carbon dioxide would no longer be cleaned out of the air, and—as it trapped heat—Earth might warm up fast. And, perhaps most problematic, almost every living thing on Earth would eventually run out of food and die.

Why would this be the case? In almost all ecosystems, photosynthesizers are the only "gateway" for energy to flow into food webs—networks of organisms that eat one another. If photosynthesizers were removed, the flow of energy would be cut off, and the other organisms would run out of food. In this way, photosynthesizers lay the foundation for every light-receiving ecosystem.

Producers are the energy gateway

Plants, algae, and photosynthetic bacteria act as producers. Producers are autotrophs, or self-feeding organisms, that make their own organic molecules from carbon dioxide. Photoautotrophs, like plants, use light energy to build sugars out of carbon dioxide. The energy is stored in the chemical bonds of the molecules, which are used as fuel and building material by the plant.

The energy stored in organic molecules can be passed to other organisms in the ecosystem when those organisms eat plants or other organisms that have previously eaten plants. In this way, all the consumers—or heterotrophs, other-feeding organisms—of an ecosystem rely on the ecosystem's producers for energy. Consumers include herbivores, carnivores, and decomposers.

E-mails do not require professionalism; it's acceptable to be informal. true or false
Umnica [9.8K]
It depends. In most cases emails kind of have a professional stigma following them and are sent to ask questions or to gain information or inform the receiver so it’s best presented in a formal way.
In other cases such as a letter to a friend it can be as informal as the writer would like. Overall though I would say False, emails require professionalism.

How did the battles change the course of the war? Which side had a favorable outcome for the battles?
seropon [69]

Two large armies met in the southern Pennsylvanian town of Gettysburg in the early days of July 1863. The engagement, which started as a skirmish between Union cavalry and Confederate troops searching for supplies, turned into one of the Civil War's bloodiest conflicts.

The final Union triumph at Gettysburg would significantly improve North morale and put a stop to Confederate General Robert E. Lee's audacious plan to invade the North. The fight, which is frequently cited as a crucial turning point in the conflict, would gain even more significance later that year when President Abraham Lincoln visited Gettysburg to dedicate the cemetery on the battlefield.

The cavalry regiments were scouting ahead to learn more about the enemy position even while the majority of the Army of the Potomac was still in Maryland, following Lincoln's instructions to remain in Maryland to maintain a buffer between Washington and the rebel army. The Confederate soldiers originally withdrew to Cashtown, but on July 1 they made the decision to return to Gettysburg and acquire the supplies they required, even if it meant confronting the Union troop.
