Angiosperms, flowering plants, and gymnosperms, cone-bearing plants, reproduce using egg, sperm, and produce seeds. In gymnosper
Mnenie [13.5K]

The most common way these trees undergo pollination is through seeds and pollen.

The pollination is done with help of wind and birds where pollen transform from one plant to another.

<u>Explanation:</u>

The plants that undergoes pollination process through the seeds that are present in it are called as Angiosperms. These contains fruits. The seeds are usually present inside these fruits. Flowering plants are also called as Angiosperms.

These fruits and flowers are absent in gymnosperm. Even then they contain seeds inside the leaves surface. They will undergo pollination with these naked seeds. It is the fruits, flowers and the endosperm that are present in the seeds that help us to find difference between these two.  The only common thing that exists between these two are seeds and pollen with which they pollinate.

In gymnosperms, pollen is transferred from male cone to female cone through wind or birds. Now, the pollen is germinated into pollen tubes and sperm for egg fertilization.

Use the model here to describe the transfer of matter and flow of energy from one trophic level to another within an ecosystem.
Brrunno [24]

Answer:

A)Biomass is transferred from one organism to another when one organism consumes another organism. When a predator organism eats the prey organism, the molecules on the food are broken down by the digestive system into smaller molecules. These smaller molecules like lipids, amino acids, glucose are used by the organism for various purposes.

B) Energy that is not transferred from one organism to another is either used up by the organism for various purposes. Most of the energy is lost into the environment in the form of heat.

c) There are typically fewer organisms at the top of the trophic levels because energy keeps on declining at each trophic levels so the number of consumers which it can satisfy also decreases.

d) Only 10% of the energy passes from one trophic level to another. The rest is usually lost in the form of heat. For example, if there was 100%  energy in the producers, only 10% would pass to the primary consumers. The secondary consumers will receive 1%.

How do CAM plants differ from C3 and C4
algol13

Answer:

C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.
