The correct Answer is:
To solve the question, we need to fill in the blanks based on the provided statements. Let's analyze each statement one by one: ### Step 1: Analyze the first statement **Statement I:** A ______ food chain begins with dead organic matter. - There are two types of food chains: grazing food chains and detritus food chains. - The grazing food chain starts with producers (plants), while the detritus food chain starts with dead organic matter. - Therefore, the correct term to fill in the blank is **"detritus."** ### Step 2: Analyze the second statement **Statement II:** In xerarch succession, the series progresses from ______ conditions. - Xerarch succession occurs in dry environments, and it typically progresses from xeric (dry) conditions to mesic (moist) conditions. - Thus, the correct term to fill in the blank is **"xeric."** ### Step 3: Analyze the third statement **Statement III:** Breaking down of detritus into small particles by earthworm is called ______. - The process of breaking down detritus into smaller particles is known as fragmentation. - Earthworms play a crucial role in this process as they consume detritus and break it down into smaller pieces. - Therefore, the correct term to fill in the blank is **"fragmentation."** ### Final Answer Based on the analysis, the filled statements are: I. A **detritus** food chain begins with dead organic matter. II. In xerarch succession, the series progresses from **xeric** conditions. III. Breaking down of detritus into small particles by earthworm is called **fragmentation.**
