Answer:
These chemical reactions produce waste products such as carbon dioxide, water, salts, urea and uric acid. Accumulation of these wastes beyond a level inside the body is harmful to the body. The excretory organs remove these wastes. This process of removal of metabolic waste from the body is known as excretion.
Vacuoles store the materials needed for the cell.
Trees blowing in the wind, bees landing on flowers, bunnies hopping on grass
D. diversity of the resources in the habitat.
Explanation:
The deforestation brings in lot of problem, much more than it brings in benefits for the humans on the long run. Once a forest is totally destroyed, the habitat suddenly loses the majority of its resources, especially for the organisms that are consumers. The soil too gets rapidly degraded, so the majority of the producers too find it very hard and takes them long time to reestablish themselves.
Having the diversity of resources dwindle, the organisms suffer badly. All living creates need resources in order to survive, so once they don't have them they die out. This unfortunately happens all over the world, with the tropical rainforest habitats being the most endangered, especially in the Amazon, Congo, and Southeast Asia.
Answer:
Electromagnetic waves can travel through a vacuum, that is an empty space, whereas mechanical waves cannot. They need a medium to travel such as water or air. Ripples in a pond are an example of mechanical waves whereas electromagnetic waves include light and radio signals, which can travel through the vacuum of space.
