Cause and effect relationships can be suggested and predicted for complex natural and human designed systems by examining what is known about smaller scale mechanisms within the system. Introduction This lesson is the final test and summative assessment for the biomes unit. The test consists of 25 multiple choice questions, and a short essay which students can write on their choice of 1 of any 4 short answer prompts. Please note that all of the sections below are timed at 0 minutes.

Some of the major biomes of the world are as follows: Rain Forest Biome 4. Deciduous Forest Biome 5. A desert usually has less than 25 cm of rain per year. Nights are generally cold, even in summers, and daily variations in temperature reach extremes found in no other environment.

Desert life is usually well adapted to the dry weather. Most annual plants in the desert are small.

Ecosystems- This essay covers every major biome in biology, addresses every key term in Enviromental Biology, and gives great illistrations of each biome. Sahara desert every year because of 3/5(6). A biome is made up of many different ecosystems. The ecosystems tend to have the same pants and animals as neighboring biomes around the boundaries. The major biomes are the tundra, taiga, tropical rain forest, temperate forests, desert, grassland, savanna, chaparral, and marine. The Pacific Ocean is the world’s largest ocean, which covers about one-third of the Earth’s exterior. According to the book Oceans (Hutchinson, ) this ocean has the greatest average depth of 13, feet and also has the deepest point in the ocean, which is 36, feet/5(1).

They grow rapidly, bloom and produce seeds all within a few days after a rain. Since the growing season is greatly restricted, such plants live relatively small.

Many perennial desert plants have small leaves, or none at all, or their leaf surfaces are often reduced to spines and thorns, minimizing water loss by evaporation. Some have very long roots, reaching deeply buried water. Others, like the cacti, absorb water rapidly after a rain and store the same in spongy internal tissues.

Desert animals are also adapted to scarcity of water and extremes of temperature. In most deserts, the large homoeothermic mammals and birds are comparatively rare or are absent altogether because the maintenance of a constant body temperature is difficult or rather impossible under conditions of extreme heat and practically no water.

However, some animals like the camel are adapted to extreme desert conditions. Animals, which match their internal temperature to that of their environment, the so-called cold-blooded animals, live more easily in the desert.

Desert animals are generally small, and they include many burrowing forms, which may avoid the direct heat of the Sun.

In all deserts small rodents are numerous and almost all are burrowers. The kangaroo rat Dipodomys is a desert animal depending on bipedal, leaping locomotion.

Snakes and lizards are common in all deserts. In a grassland biome, the vegetation is dominated by grasses, which may grow to about 2 m in the moist areas and 0.

It is not an exclusively tropical biome but extends into much of the temperate zone as well. The common feature of all grasslands is intermittent, erratic rainfall, amounting to about 4 to 16 cm annually.

The irregularly of rain, porosity and drainage of the soil, or both factors together prevent a continuous or ample supply of water to plant roots. Grasses of various kinds are particularly adapted to irregularly alternating periods of precipitation and dryness.

The environmental conditions vary greatly in different grasslands. There are also non-grass herbaceous species, which are called forbs. Grassland biome probably supports more species of animals than any other terrestrial habitat. In all grasslands, the primary consumers are the large grazing mammals like the bisons, pronghoms Antilocapra Americana and zebra Equus zebra.

African glass-lands support large herds of zebras and several species of grazing antelopes. The grassland ungulates are cursorial. Hares and rodent are also common primary consumers in the grasslands. Many rodents, like the prairie dogs and other ground squirrels or the pocket gophers, are burrowing or fossorial animals.

Australian grasslands have herbivores very different in appearance and relationships but ecologically similar. Predators are adapted to the herbivore prey:Examples of the earth’s major biological communities will be provided to show students how climate influences the types of organisms that live in a particular place, and that similar types of ecosystems occur all over the world.

Answer Key: Biomes Unit Test Grading the Short Answer My current Environmental Science course is not AP, but I would eventually like to offer an AP Environmental Science course to my students.

A biome is NOT an ecosystem. If you take a closer look, you will notice that different plants or animals in a biome have similar adaptations that make it possible for them to exist in that area.

There are many major biomes on earth.
