Explain the concept of parasitism and provide two examples of parasitic relationships in nature.
Parasitism is a type of symbiotic relationship where one organism, called the parasite, benefits at the expense of another organism, called the host.

Two examples of parasitic relationships are ticks feeding on the blood of mammals and mistletoe plants deriving nutrients from trees.

Describe the role of autotrophs in an ecosystem and provide two examples of autotrophs.
Autotrophs, also known as producers, are organisms that can produce their own food through photosynthesis or chemosynthesis. They are the foundation of the food chain, as they convert energy from sunlight or inorganic compounds into organic matter. Two examples of autotrophs are plants that use photosynthesis to produce glucose and bacteria that use chemosynthesis to convert chemicals into energy.
