    Around these trees, you often see parrots feeding on mangoes, mynas perching on neem branches, and sparrows nesting in banyan trees. Insects like honeybees pollinate flowers, ants scavenge for food, and butterflies flutter around for nectar. These interactions create a dynamic ecosystem where birds and insects rely on trees for food and shelter, while trees benefit from their roles in pollination, seed dispersal, and maintaining ecological balance.

    Native plants like neem (Azadirachta indica) and banyan (Ficus benghalensis) thrive, contributing significantly to the ecosystem. However, rare plants like sandalwood (Santalum album) and tulsi (Ocimum tenuiflorum) are under threat from habitat destruction and overharvesting. These plants have cultural, medicinal, and ecological importance, making their conservation crucial. Efforts like creating awareness and promoting plantation drives can help protect these endangered species for future generations.

    Agricultural fields near the area predominantly grow rice during the monsoon, wheat in winter, and sugarcane throughout the year. These crops depend on specific climatic conditions for optimal growth, with rice requiring heavy rainfall and wheat thriving in cooler temperatures. Seasonal farming not only supports local biodiversity but also maintains soil fertility and ensures year-round food production, highlighting the interconnectedness of agriculture and the environment.

    Weeds like Bermuda grass compete with crops for sunlight, water, and nutrients, reducing agricultural productivity. Pests such as aphids infest plants, sucking sap from leaves and stems, which leads to stunted growth and reduced yields. These pests also make plants more susceptible to fungal and bacterial infections. Identifying and managing weeds and pests is crucial to safeguarding crops and ensuring the sustainability of agricultural biodiversity.

  5. Let's analyze the energy transfer to solve this problem. Step 1: Energy released by X g of steam When steam at 100°C condenses to water at 100°C, the energy released is: Qₛₜₑₐₘ = X ⋅ Lᵥ where Lᵥ = 540 cal/g (latent heat of vaporization of water). Step 2: Energy absorbed by Y g of ice The ice first mRead more

    Let’s analyze the energy transfer to solve this problem.

    Step 1: Energy released by X g of steam
    When steam at 100°C condenses to water at 100°C, the energy released is:
    Qₛₜₑₐₘ = X ⋅ Lᵥ
    where Lᵥ = 540 cal/g (latent heat of vaporization of water).

    Step 2: Energy absorbed by Y g of ice
    The ice first melts into water at 0°C, and then this water is heated to 100°C. The total energy absorbed by Y g of ice is:
    Qᵢcₑ = Y ⋅ Lf + Y ⋅ c ⋅ ΔT

    where:
    – Lf = 80 cal/g (latent heat of fusion of ice),
    – c = 1 cal/g°C (specific heat capacity of water),
    – ΔT = 100°C.

    Put values:
    Qᵢcₑ = Y ⋅ 80 + Y ⋅ 1 ⋅ 100 = Y ⋅ (80 + 100) = Y ⋅ 180 cal.

    Step 3: Energy conservation

    The energy released by steam is equal to the energy absorbed by ice:
    X ⋅ 540 = Y ⋅ 180

    Step 4: Solve for X/Y
    X / Y = 180 / 540 = 1 / 3

    Final Answer:
    The ratio of X and Y is 1:3.
