You're on a roll — Q6: One of the main negative effects of continuous cropping practices on the local ecological environment is the decrease in soil fertility over time.
Q7: The crops found in Group Y (Peppers, Chillies, Ginger) are called spices.
Q8: Step 1: Examine the crops listed in each group and consider major agricultural commodities grown in Papua New Guinea. Major commodities include sweet potato, taro, yam, coffee, cocoa, coconut, and oil palm. Step 2: Evaluate the groups for a complete list of three major commodities. • Group V contains Yam, Irish potatoes, and Taro. Yam and Taro are major staple crops in PNG. Irish potatoes are also grown. This group provides a plausible list of three significant food crops. • Group X contains Coffee, Tea, and Cocoa. Coffee and Cocoa are major cash crops, but Tea is less significant compared to the others. • Group Z contains Coconut, Oil palm, and Sunflower. Coconut and Oil palm are major cash crops, but Sunflower is not a major commodity in PNG. Step 3: Based on the prevalence of these crops as staples and cash crops in PNG, Group V offers the most consistent list of three major agricultural commodities. The group that contains a complete list of three major agricultural commodities grown in Papua New Guinea is Group V.
Q9: Group U contains a list of crops (Winged bean, peanut, Bambara nut) that are an important part of the nitrogen cycle.
Q10: Step 1: Define Xylem. Xylem is a plant tissue responsible for the transport of water and dissolved minerals from the roots upwards to the rest of the plant. It also provides structural support. Step 2: Define Phloem. Phloem is a plant tissue responsible for the transport of sugars (food) produced during photosynthesis from the leaves to other parts of the plant where they are needed for growth or storage. The difference between xylem and phloem is their primary function in transport: • Xylem transports water and minerals from roots to leaves. • Phloem transports sugars (food) from leaves to other parts of the plant.
