Q33. Which kingdom includes organisms that are primarily multicellular, heterotrophic, and obtain nutrients through absorption of decomposed organic matter?
a) Plantae
b) Animalia
c) Fungi
d) Protista
Show Answer
Correct Answer: c) Fungi
Explanation: Fungi are multicellular, heterotrophic organisms that obtain nutrients through absorption of decomposed organic matter. They play crucial roles in nutrient cycling and decomposition in ecosystems.
Q34. Organisms in which kingdom are characterized by their ability to move by means of cilia, flagella, or pseudopodia, and they include amoebas, paramecia, and euglenas?
a) Animalia
b) Plantae
c) Fungi
d) Protista
Show Answer
Correct Answer: d) Protista
Explanation: Protists are eukaryotic organisms that exhibit diverse forms of locomotion, including ciliary movement, flagellar propulsion, and pseudopodial crawling. They belong to the kingdom Protista.
Q35. Which kingdom encompasses multicellular, eukaryotic organisms that obtain nutrients through ingestion and digestion in an internal digestive cavity?
a) Monera
b) Plantae
c) Animalia
d) Protista
Show Answer
Correct Answer: c) Animalia
Explanation: Animals are multicellular, eukaryotic organisms belonging to the kingdom Animalia. They obtain nutrients through ingestion and digestion in an internal digestive cavity.
Q36. Organisms in which kingdom are primarily multicellular, photosynthetic, and possess cell walls made of cellulose?
a) Animalia
b) Plantae
c) Fungi
d) Protista
Show Answer
Correct Answer: b) Plantae
Explanation: Plants are multicellular, photosynthetic organisms belonging to the kingdom Plantae. They possess cell walls made of cellulose and play vital roles in ecosystems as primary producers.

Q38. Organisms in which kingdom are characterized by their ability to decompose organic matter, possess cell walls made of chitin, and obtain nutrients through extracellular digestion?
a) Animalia
b) Plantae
c) Fungi
d) Protista
Show Answer
Correct Answer: c) Fungi
Explanation: Fungi are heterotrophic organisms that decompose organic matter, possess cell walls made of chitin, and obtain nutrients through extracellular digestion by secreting enzymes.
Q39. Which kingdom encompasses organisms that are primarily multicellular, eukaryotic, and possess specialized structures for photosynthesis, such as chloroplasts?
a) Animalia
b) Plantae
c) Fungi
d) Protista
Show Answer
Correct Answer: b) Plantae
Explanation: Plants are multicellular, eukaryotic organisms belonging to the kingdom Plantae. They possess specialized structures like chloroplasts for photosynthesis and are essential in producing oxygen and food for ecosystems.
Q40. Organisms in which kingdom are primarily multicellular, heterotrophic, and exhibit absorptive nutrition by secreting enzymes to break down organic matter externally?
a) Animalia
b) Plantae
c) Fungi
d) Protista
Show Answer
Correct Answer: c) Fungi
Explanation: Fungi are multicellular, heterotrophic organisms that exhibit absorptive nutrition by secreting enzymes to break down organic matter externally. They absorb the resulting simpler compounds for nourishment.
