Final answer:
Living things require food, plants make their own food through photosynthesis, plants need oxygen, animals eat plants or other animals, and many living things require oxygen for releasing energy from food.
Step-by-step explanation:
The statement 'All living things must eat other living things for food' is true. Living things are classified into heterotrophs (organisms that obtain nutrients from other organisms) and autotrophs (organisms that can make their own food).
The statement 'Plants can make their own food' is true. Plants are autotrophs and use photosynthesis to produce their own food using sunlight, carbon dioxide, and water.
The statement 'Plants don't need oxygen, only carbon dioxide' is false. Plants, like other living things, need oxygen for cellular respiration, which is the process by which they release energy from food.
The statement 'Animals eat plants or other animals that eat plants' is true. Animals are heterotrophs and obtain energy by consuming plants or other animals.
The statement 'Many living things need oxygen to release energy from food' is true. Oxygen is necessary for cellular respiration, the process by which living organisms derive energy from food.
