Agriculture  is commonly described as the science or art of farming. What determines them is climate, temperature, cold, if seed can be sown outdoors in the spring , the ability to withstand early spring and fall frosts and winter temperatures.

Winter annuals often bloom in winter or spring. They grows in very low to the ground. Examples are henbit, deadnettle, chickweed etc. Spring annuals are known to sprout early in the spring.

Answer:

Carbon is the backbone of life on Earth. We are made of carbon, we eat carbon, and our civilizations—our economies, our homes, our means of transport—are built on carbon. We need carbon, but that need is also entwined with one of the most serious problems facing us today: global climate change.

Carbon is both the foundation of all life on Earth, and the source of the majority of energy consumed by human civilization. [Photographs ©2007 MorBCN (top) and ©2009 sarahluv (lower).]

Forged in the heart of aging stars, carbon is the fourth most abundant element in the Universe. Most of Earth’s carbon—about 65,500 billion metric tons—is stored in rocks. The rest is in the ocean, atmosphere, plants, soil, and fossil fuels.

Carbon flows between each reservoir in an exchange called the carbon cycle, which has slow and fast components. Any change in the cycle that shifts carbon out of one reservoir puts more carbon in the other reservoirs. Changes that put carbon gases into the atmosphere result in warmer temperatures on Earth.

Draft diagram of the carbon cycle.

This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans. Yellow numbers are natural fluxes, and red are human contributions in gigatons of carbon per year. White numbers indicate stored carbon. (Diagram adapted from U.S. DOE, Biological and Environmental Research Information System.)

Over the long term, the carbon cycle seems to maintain a balance that prevents all of Earth’s carbon from entering the atmosphere (as is the case on Venus) or from being stored entirely in rocks. This balance helps keep Earth’s temperature relatively stable, like a thermostat.

This thermostat works over a few hundred thousand years, as part of the slow carbon cycle. This means that for shorter time periods—tens to a hundred thousand years—the temperature of Earth can vary. And, in fact, Earth swings between ice ages and warmer interglacial periods on these time scales. Parts of the carbon cycle may even amplify these short-term temperature changes.

The global carbon cycle model describes the evolution of carbon mass in the mantle (Cm), the combined reservoir of ocean and atmosphere (Co+a), the continental crust (Cc), the ocean crust and floor (Cf), the kerogen (Cker), and the biosphere (Cbio).

Carbon on the dynamic planet can move from one of these realms to another as part of the carbon cycle.

Thus, above-mentioned are the steps involved in a carbon cycle.

Answer:

The answer is D.) Solids have the least amount of energy

Explanation:

Because in a solid, particles are packed tightly together so they don't move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their position. Because of this, particles in a solid have very low kinetic energy.

The introduction of pests in a new geographic region may have devastating consequences on crop yields. Invasive pest species often don't have natural predators or exhibit higher adaptive fitness.

Invasive species represent an important subject of concern in agriculture because they have the potential to drastically reduce crop yields.

Generally, invasive pest species don't have natural predators or exhibit higher adaptive fitness compared to well-established natural pest species.

In consequence, these species (invasive species) may cause considerable harm to crops.
