Plants, algae and phytoplankton are the main components of the carbon cycle.

Plants, algae and phytoplankton are the main components of the fast carbon cycle.

On the basis of the type of activity carbon cycle can be divided into two types:

1. Slow carbon cycle

2. Fast carbon cycle

Slow carbon cycle: It involves the synthesis of carbon through sedimentation of rocks, synthesis of fossil fuels beneath the earth. The rate of synthesis of carbon is slow in these processes.

Fast carbon cycle: It involves the synthesis of carbon through photosynthesis by autotrophs like plants, algae and phytoplankton. These autotrophs convert atmospheric carbon into glucose which is also a form of carbon, this happens at a faster rate.

the correct answer is: d. the saltine and pretzel are made of flour, yeast, and baking soda, and salt. the pecan contains no flour but it does contain fats. the pecan is a nut that can be consumed as a healthy snack. first of all, pecans are a source of fat (monounsaturated fat), but they provide less fat than some other nuts. pecans are a rich source of dietary fiber, manganese magnesium, phosphorus, thiamin, vitamin e…

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
