Match each animal with the correct classification.
a. eagle
b. ladybug
c. scorpion
d. lobster
e. snail
1. chordata phylum
2. mollusca phylum
3. arachnida class
4. crustacea class
5. insecta class

eagle- chordata phylum

ladybud- Insecta class

scorpian- Arachnida class

lobster- Crustacea class

snail- Mollusca phylum

Explanation:

The organism that contains a notochord at some of its life cycle stage are called chordates and all vertebrates are chordates so eagle comes under phylum Chordata.

Insecta is the largest class of phylum Arthropoda which contains organisms which have jointed legs, exoskeleton and segmented body for example ladybird, playing mantis, etc.

Arachnids are animals which have jointed legs and in this class spider are the largest order which contains scorpions, mites, ticks, etc.

Crustaceans are invertebrates which have hard shell made up of calcium for example lobster, prawn, shrimp, etc.

Mollusks are very large invertebrate phylum which contains a soft segmented body that is usually present inside a shell made up of calcium. for example snails.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
