offspring, sharing similar characteristics.
How does the concept of a kingdom fit into biological classification?
✔✔A kingdom is one of the highest levels in the biological classification system, grouping
organisms based on fundamental traits such as cell structure and methods of obtaining energy.
What is the difference between autotrophs and heterotrophs?
✔✔Autotrophs produce their own food through processes like photosynthesis, while
heterotrophs obtain energy by consuming other organisms.
What is the primary role of fungi in ecosystems?
✔✔Fungi primarily act as decomposers, breaking down dead organic material and recycling
nutrients back into the ecosystem.

,Why are viruses not classified within any of the five kingdoms?

organelles, unlike prokaryotes, which lack these structures.
Which kingdom includes multicellular organisms that are mostly decomposers?
✔✔The Fungi kingdom includes mostly multicellular decomposers that absorb nutrients from
organic material.
Why is the Protista kingdom considered a diverse group?
✔✔The Protista kingdom is highly diverse because it includes organisms that can be similar to
plants, animals, or fungi but don’t fit neatly into those kingdoms.
What role do plants play in the ecosystem as members of the Plantae kingdom?
✔✔Plants produce oxygen through photosynthesis and form the base of food chains, supplying
energy to other organisms.
How do scientists differentiate between species?
✔✔Scientists differentiate between species based on reproductive compatibility, genetic
differences, and unique physical or behavioral traits.
