II-hypocotyl
III-stem
IV-margin
V-midrib
VI-node/leaf stalk
VII-inflorescense
VIII-leaf
1aii)
I-it carries out reproduction
II-it provides a space for the growth of flower
V-holds other part of the leaf together
VIII-aids the absorption of sunlight ie the photosynthesis
1bi)
A-Monocotyledon
B-Dicotyledon
1bii)
A-it has one seed leaf
-it has a parallel vein
B-leaf has net vein
-it has two seeded leaf
1c)
A-rice,oil palm
B-groundnut,cowpea,mango
1di)
-A has parallel vein while B has net vein
-A has one seed leaf while B has two seed leaves
-A has vibrous root while B has tap root
-A has the female and male parts of the flower at different part while B has both the male and female parts at the same part of the flower
-A is a grass with long and narrow leaves while B is a legume with broad leaves
1dii)
-They are both flowering plants
-They are both seed plants
-They are both vascular plants
2a)
Food web
2b)
Producer(grass)->primary consumer(cane rat,grasshopper,mouse)->secondary consumer(fox,lizard,snake)->tertiary consumer(man,hawk,Eagle)
2ci)
I-The population of the lizards will increase
II-More energy would be passed into the chain in the web containing grasshopper,lizards,hawk and man
III-Less energy might be available to mouse
I-The population of lizards would decrease
II-Less energy would be passed into the chain containing lizards
III-more energy would be available to mouse and cane rat
