6th Grade Intro To Biomes And Relationships

Deserts are known for their extreme arid conditions and lack of rainfall. These conditions make it difficult for most plants to survive, but cacti and small bushes have adapted to store water and withstand the harsh environment. They have evolved to have thick stems or spines to reduce water loss and can survive in sandy or rocky soil. Therefore, the presence of cacti and small bushes is a characteristic feature of desert biomes.

Lions, giraffes, and elephants are commonly found in the savanna biome of Africa. The savanna is characterized by vast grasslands with scattered trees and is home to a diverse range of wildlife. This biome provides the perfect habitat for these animals as they can find ample food, water, and shelter in this open landscape. The savanna's warm climate and seasonal rainfall also support the growth of grasses, which is a primary food source for these herbivores. Additionally, the savanna's open terrain allows for easier hunting and movement for lions, making it an ideal habitat for them as well.

Tropical rain forests receive the most precipitation compared to the other biomes listed. This is because they are located in regions near the equator where warm air rises, causing heavy rainfall. The high amount of rainfall in tropical rain forests supports the growth of diverse plant and animal species, making them one of the most biodiverse ecosystems on Earth.

The correct answer is sun because producers, such as plants and algae, undergo photosynthesis to convert sunlight into energy. This process allows them to produce their own food and sustain themselves. Without sunlight, producers would not be able to carry out photosynthesis and obtain the energy needed for growth and survival.

The diagram does not provide any information about the deer's ability to produce its own food or its position in the food chain. However, as a primary consumer, the deer is likely to consume plants or other organisms that are producers, making it a correct answer choice.

The base of any food chain or web is producers. Producers, such as plants and algae, are able to convert sunlight into energy through photosynthesis. They are the primary source of food and energy for all other organisms in the ecosystem. Without producers, there would be no energy available for consumers, predators, or prey, and the food chain/web would collapse.

The correct answer is tundra because it is the biome characterized by extremely cold temperatures and a layer of permanently frozen soil called permafrost. This frozen ground prevents water from draining and limits the growth of trees and other vegetation. The tundra is found in the Arctic regions of the world, such as Alaska, Canada, and Siberia.

Deciduous refers to trees that shed their leaves annually, typically in the fall season, and then regrow new leaves in the spring. This natural process allows deciduous trees to adapt to changing seasons and conserve energy during the colder months. Unlike evergreen trees, which retain their leaves year-round, deciduous trees experience a cycle of leaf loss and regrowth as part of their life cycle. This characteristic is a defining feature of deciduous trees.

The eastern part of the United States is characterized by a temperate deciduous forest biome. This biome is known for its moderate climate and four distinct seasons. The region is home to a variety of deciduous trees such as oak, maple, and beech, which shed their leaves in the fall. The temperate deciduous forest biome is also known for its rich biodiversity, with a wide range of plant and animal species. This explanation fits the given correct answer.

The living part of an ecosystem refers to all the organisms that inhabit it, including plants, animals, and microorganisms. These organisms interact with each other and their environment, playing a crucial role in the functioning of the ecosystem. Therefore, the term "biotic factors" accurately describes the living components of an ecosystem.

The correct answer suggests that there must be a number of predators since the number of prey is decreasing. This is because in a predator-prey relationship, as the number of predators increases, they consume more prey, leading to a decrease in the prey population. Therefore, the decrease in the number of prey indicates the presence of predators.

Bacteria and fungi have the role as decomposers because they break down dead organic matter and recycle nutrients back into the ecosystem. They play a crucial role in the decomposition process, breaking down complex organic compounds into simpler forms that can be used by other organisms. By decomposing dead plants and animals, bacteria and fungi help to release nutrients such as nitrogen, phosphorus, and carbon back into the soil, making them available for other organisms to use. Without decomposers, organic matter would accumulate and nutrients would be locked away, leading to a disruption in the nutrient cycle and ecosystem functioning.

The largest biome on Earth is the marine biome. This biome encompasses all the bodies of saltwater, including oceans, seas, and estuaries. It covers about 70% of the Earth's surface and is home to a wide variety of organisms, including fish, whales, dolphins, coral reefs, and plankton. The marine biome plays a crucial role in regulating the Earth's climate, providing oxygen, and supporting numerous ecosystems and food chains.

Understanding food webs is important because it allows people to comprehend how their actions can impact the delicate balance of nature. By understanding the interconnectedness of different organisms and their roles in the ecosystem, people can make informed decisions to minimize their negative impact and promote sustainability. This knowledge helps individuals recognize the consequences of their actions and take steps towards preserving the environment for future generations.

The correct answer is tundra and desert. Both tundra and desert biomes receive very little rainfall. Tundra is characterized by extremely cold temperatures and a short growing season, while deserts are known for their arid conditions and lack of vegetation. In both biomes, the scarcity of rainfall limits the availability of water and contributes to the unique adaptations of plants and animals to survive in these harsh environments.
