To determine the correct answer for each question and explanation:
1. Which contains only abiotic factors?
To answer this question, we need to identify the options that consist solely of abiotic factors. Abiotic factors refer to non-living components of an ecosystem. Let's analyze each option:
A. Firewood, wind, and fish: Firewood is a biotic factor since it comes from living organisms. Therefore, this option includes both biotic and abiotic factors.
B. Water, wind, and soil: Water, wind, and soil are all abiotic factors. This option contains only abiotic factors, so it is a correct answer.
C. Rocks, soil, and grass: Rocks and soil are abiotic factors, but grass is a biotic factor. Therefore, this option includes both biotic and abiotic factors.
D. Water, grass, and firewood: Water and firewood are abiotic factors, but grass is a biotic factor. This option includes both biotic and abiotic factors.
From the analysis above, we can determine that option B, which includes water, wind, and soil, contains only abiotic factors.
2. Which is not a type of grassland?
To find the answer, we need to identify which option does not belong to the category of grasslands.
A. Savanna: Savanna is a type of grassland found in tropical regions, characterized by a mixture of grasses and scattered trees. Therefore, savanna is a type of grassland.
B. Plains: Plains are low-lying areas characterized by flat or gently rolling landscapes covered primarily by grass. Plains are indeed a type of grassland.
C. Prairie: A prairie is a large, open grassland ecosystem found in North America. Prairie is also a type of grassland.
D. Sahara: The Sahara is a desert, not a grassland. It is characterized by vast stretches of arid land with little vegetation, primarily dominated by sand. Therefore, Sahara is not a type of grassland.
From the analysis above, we can determine that option D, Sahara, is not a type of grassland.
3. Which is not a characteristic of grasslands?
To identify the characteristic that doesn't belong to grasslands, we need to analyze each option.
A. Dry/not a lot of rain: Grasslands are characterized by dry climates with limited rainfall. Therefore, this is a characteristic of grasslands.
B. Warmer climate: Grasslands tend to have a warmer climate compared to other biomes like forests or tundra. This is a characteristic of grasslands.
C. Lots of trees: Grasslands are typically treeless or have very few scattered trees. Therefore, this is not a characteristic of grasslands.
D. Has grazing mammals: Grasslands are home to various grazing mammals like zebras, antelopes, or bison. This is a characteristic of grasslands.
From the analysis above, we can determine that option C, lots of trees, is not a characteristic of grasslands.
