At 137°C and under a pressure of 6.22 ATM, A 276 g sample of Radon occupies what

Producer: Plants, trees, chemosynthetic bacteria

Consumers: Grasshoppers, Deer , Lions

Explanation:

The terms producers and consumers are used when we are studying the food chains etc.

In a food chain there are different levels which are linked with each other based on their food requirements.

The food chain starts with producers, the organism which produces their own food either in presence of sunlight or absence of sunlight with other chemicals

Example of producers are: Trees, phytoplanktons, chemosynthetic bacteria.

Then the food synthesized by producers is being consumed by the next stage organism of the food chain known as consumers. These include the herbivores which are primary consumers as they feed on the plants and then carnivores which are secondary consumers as they feed on the primary consumers.

Example : Deer is a primary consumers

Lion is a secondary consumer.
