Chromosomes are thread-like structures present in the nucleus, which carries genetic information from one generation to another. They play a vital role in cell division, heredity, variation, mutation, repair and regeneration.
Condensation is when the water vapor changes into water droplets
The main source of carbon dioxide in an ecosystem is the carbon dioxide gas present in the atmosphere. This carbon dioxide is used by the plants and animals in different ways.
The plants use this carbon dioxide to perform the process of photosynthesis.This is carried out by the help of green pigment called chlorophyll that absorbs light from the sun, water from soil and carbon dioxide from atmosphere.
The carbon in animals comes when they eat these plants.
There are a few very good reasons why the change in the ice mass results in a decline in the populations of penguins. One reason is the penguins food source grows and develops under the the ice masses. Another reason is a loss of habitat for the penguins. When there is less ice, there are fewer krill for the penguins to eat.
An omnivore eats both plants and animals!
Badgers, pandas, raccoons, and dogs are examples of omnivores I think!
