An energy pyramid is a graphical model of energy flow in a community. The different levels represent different groups of organis

ms that compose a food chain. An energy pyramid’s shape shows how the amount of useful energy that enters each level. Chemical energy, in the form of food, decreases because some is used by the organisms in each level. The source of the chemical energy is the producers, that rearrange carbon dioxide and water in the presence of light to make ________ through the process of ______________.

What are 5 major results of global climate change ​
Sindrei [870]

Answer:

Change Will Continue Through This Century and Beyond

Global climate is projected to continue to change over this century and beyond. The magnitude of climate change beyond the next few decades depends primarily on the amount of heat-trapping gases emitted globally, and how sensitive the Earth’s climate is to those emissions.

Temperatures Will Continue to Rise

Because human-induced warming is superimposed on a naturally varying climate, the temperature rise has not been, and will not be, uniform or smooth across the country or over time.

Frost-free Season (and Growing Season) will Lengthen

The length of the frost-free season (and the corresponding growing season) has been increasing nationally since the 1980s, with the largest increases occurring in the western United States, affecting ecosystems and agriculture. Across the United States, the growing season is projected to continue to lengthen.

In a future in which heat-trapping gas emissions continue to grow, increases of a month or more in the lengths of the frost-free and growing seasons are projected across most of the U.S. by the end of the century, with slightly smaller increases in the northern Great Plains. The largest increases in the frost-free season (more than eight weeks) are projected for the western U.S., particularly in high elevation and coastal areas. The increases will be considerably smaller if heat-trapping gas emissions are reduced.

Changes in Precipitation Patterns

Average U.S. precipitation has increased since 1900, but some areas have had increases greater than the national average, and some areas have had decreases. More winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century.

Projections of future climate over the U.S. suggest that the recent trend towards increased heavy precipitation events will continue. This trend is projected to occur even in regions where total precipitation is expected to decrease, such as the Southwest.

More Droughts and Heat Waves

Droughts in the Southwest and heat waves (periods of abnormally hot weather lasting days to weeks) everywhere are projected to become more intense, and cold waves less intense everywhere.

Summer temperatures are projected to continue rising, and a reduction of soil moisture, which exacerbates heat waves, is projected for much of the western and central U.S. in summer. By the end of this century, what have been once-in-20-year extreme heat days (one-day events) are projected to occur every two or three years over most of the nation.

Hurricanes Will Become Stronger and More Intense

The intensity, frequency and duration of North Atlantic hurricanes, as well as the frequency of the strongest (Category 4 and 5) hurricanes, have all increased since the early 1980s. The relative contributions of human and natural causes to these increases are still uncertain. Hurricane-associated storm intensity and rainfall rates are projected to increase as the climate continues to warm.

How long is a rat's large intestine and small intestine in cm? and why is one bigger than the other?
Nitella [24]

Answer;

The large intestine is much wider than the small intestine, but it is also much shorter. The small intestine is the longest part of the digestive system.


Explanation;

The small intestine is a muscular tube with three parts; the duodenum breaks down the food, the jejunum and the ileum absorb nutrients and send them into the bloodstream.

The reason why the small intestine is longer than the large intestine and any other part of the digestive system is to ensure maximum and complete absorption of nutrients to the blood stream.
