I could help you with any other questions for this if you have any.
To answer the first question, you need to understand the concept of a food chain or food web, which represents the transfer of energy and nutrients through different levels of organisms. In this scenario, the kestrel is consuming a mouse that eats grass. The mouse is considered a first-level consumer because it directly consumes the grass, which is a producer. Therefore, the correct answer is c) first-level consumer.
To answer the second question, you need to understand how producers obtain nitrogen. Producers, such as plants, need nitrogen to grow and carry out essential biological processes. In this case, the best explanation is c) plants absorb nitrogen compounds from the soil. Plants have specialized structures, such as root systems, that allow them to absorb nitrogen compounds from the soil, which they use to synthesize proteins and other nitrogen-containing molecules.
