Give typing answer with explanation and conclusion The transition to white soil near the end of the video showed the sudden appearance of new, endemic, plant species and poor growth of plant species that had dominated the previous ecosystems. What factor was most important in producing this change in the plant community? A. nutrient content of the soil B. soil chemistry C. presence or absence of nonvascular green plants

Please choose all applicable options. a.The difference in color (red versus blue) corresponds to a difference in an abiotic factor. b.The difference in color intensity (dark red versus light red) corresponds to a difference in a biotic factor. c.The difference in color (red versus blue) corresponds to a difference in a biotic factor. d.The difference in color intensity (dark red versus light red) corresponds to a difference in an abiotic factor.
The two pictures below are two soil profiles that typically form in under different types of vegetation, but can also occur relatively close together: 20 40 First, using morphological clues learned in lab, define what these two soil orders are. Be sure to indicate which soil is which (e.g., "the soil of the left is."). Then describe which CIORPT factor and which soil forming.process is probably most important in determining the difference between these two soil types are fairly close to one another?
Think about how humans rely on soil. From a human point of view, how has glaciation had a good and bad effect on Canada’s soils? A soil can include particles ranging in size from very fine clay to coarse sand. Why is neither of these soils ideal for plant growth, including agriculture?
Give typing answer with explanation and conclusion 11. Which of the following would you consider most fragile (or least stable): an alpine tundra or a grassland? Why? (please write a decent amount).
Which factors affect soil quality? a. chemical composition b. history of the soil c. presence of living organisms and topography d. all of the above
Pick 3 biomes and describe their soil and why is their this soil composition like?

Refer to the figure or diagram to answer the question. Where explanation or discussion is required, support your answers with relevant information and/or specific examples. EFFECT OF PERCENT SLOPE ON ANNUAL EROSION FOR FOUR AGRICULTURAL PRACTICES 30 25 Tillage No-till 20 No-till + cover crop 15 Crop rotation 10 -T- tolerable loss 10 25 30 15 20 Slope (%) Soil erosion is one of the most serious soil-degrading processes. Each year tons of soil erode from cropland, pastures, forests, and other places. The amount of erosion varies dramatically among various land-use types. The figure above shows the effects of different agricultural practices and slopes on annual erosion rates. (a) Refer to the graph above for the following. (1) Identify the scientific question that resulted in the data presented in the graph. (H) Identify the agricultural practice that could be used on a 15% slope without leading to a higher than tolerable loss of soil (ii) Describe the effect of adding a cover crop…
Use the information to answer the following question. A D You wake up one morning and look out your window to discover that a large fairy ring has sprung up overnight. Locations a-D represent mycelia that lies 0.5 meters below the soil's surface. Which location is nearest to basidiocarps? A C
Discuss the following prompt: In this experiment, we are looking to see how much different types of soil will affect the time it takes for pinto Bean seedlings to germinate out of the ground. The scientific name of a pinto bean is Phaseolus vulgaris. Pinto beans are kind of beans people usually eating, and people commonly use pinto beans in many dishes, such as rice and pasta. Planting pinto beans need many necessary factors, however, I think the type of soil is the most important one to grow it faster. Pinto beans are kind of plants can grow in dark and dry area, so even in dark (less light), they can grow as well. The goal is to determine that soils have different characteristics that can help or hurt plant growth. In order to discover the effects soils have on plant growth, three different soil samples will be used in a controlled study. The samples will vary in consistency, texture, color, location, moisture, and contact with human life to ensure that the samples are…
