Verified step by step guidance1
Step 1: Understand the concept of a primary producer. Primary producers are organisms that can produce their own food through processes like photosynthesis or chemosynthesis. They form the base of the food chain and provide energy for other organisms.
Step 2: Identify the characteristics of the listed organisms. Frogs are consumers that rely on other organisms for food. Mushrooms are decomposers that break down organic matter. Grass is a plant that uses photosynthesis to produce its own food, making it a primary producer. Hawks are predators that consume other animals.
Step 3: Recall the process of photosynthesis. Plants like grass use sunlight, water, and carbon dioxide to produce glucose and oxygen. This ability to create their own food classifies them as primary producers.
Step 4: Compare the roles of the organisms in the ecosystem. Grass provides energy for herbivores and other organisms, while frogs, mushrooms, and hawks depend on other organisms for energy.
Step 5: Conclude that grass is the correct answer because it fits the definition of a primary producer, unlike the other organisms listed.
