Immotile flowering plants accomplish fertilization with the help of Insects and other pollen from organisms that carry pollen to other flowers.
Explanation:
- The transfer of pollen from anther to the stigma of flower is called pollination.
- Pollination is of two types: a) Self pollination b) cross-pollination
- Transfer of pollen from anther to the stigma of same flower or flower of same plant is called self pollination.
- Transfer of pollen from anther to the stigma of different plant is called Cross-pollination.
- Pollination is the process by which angiosperms carry out sexual reproduction.
- Since, plants are immobile they need some agents for pollination like, <u>insects birds, wind, water etc </u>
<h3><u>Similarity and differences of carbon cycle in the ocean as on land:</u></h3>
- The Carbon Cycle is a biogeochemical cycle by which Carbon circulates around the planet.
- Carbon Cycle just like other cycles compromises of sequence of events that are essential to make earth capable of sustaining life.
- In land carbon is mostly circulated through photosynthesis and stored in living as well as non-living organisms.
- In oceans carbon is absorbed and dissolved into the water and get used by animals and plants.
- Ocean is like a giant sponge that soaks up more carbon than it gives.
- Like on land photosynthesis too occur in oceans and get incorporated into marine and terrestrial organisms as organic matter.
Answer:
trophic level is the answer
A. Natural Selection. This is because the weeds that are not resistant to it die out before they can reproduce, but the resistant ones grow to maturity and then reproduce, passing down the resistance gene. Over time, the resistance gene would become a normal thing in weeds, while the non-resistant gene would not exist anyone, since the gene could not be passed on.
