In a study published in the journal Nature, scientists studied eight ponds in Florida: four that were populated by a species of

fish and four that were not. As they studied the ponds, they noted that the areas around the four fish-populated ponds showed decreased populations of dragonflies and dragonfly larvae, whereas the four without fish showed abnormally large populations of dragonflies and larvae. Dragonflies feed on bees, butterflies, and other pollinators.

Answer: the rate of pollination of flower, in a field next to a pond with no fish, will DECREASE.

Explanation:

POLLINATION is defined as the process by which flowering plants, through the aid of external agents such as insects,wind, water and other animals, are able to transfer pollen grains from an anther to a receptive stigma. Insects are the most common pollinators. They visit flowers to obtain nectar and pollen as source of food. Flowers use various features, such as colour and scent, to attract and guide insects to the food source within them. In the process of reaching their source of food, insects bring about pollination.

From the study conducted by scientist in Florida, eight(8) ponds where subjected to the the study. The first four (4) ponds had species of fishes that fed on dragonflies and dragonfly larvae, hence the reason for a decrease in the population of the dragon flies in the area around it. While the remaining four (4) ponds had NO fish and the area around it is populated with dragonflies and dragonfly larvae. This is so because of the absence of fish.

It was then noted that the dragon lies fed of the insect pollinators such as the bees and butterflies. Since these dragonflies and its larvae are abundant in the field which is close to the pond with no fish, they will grossly depend on the insect pollinators as their source of food thereby decreasing the rate of pollination in the field next to the pond with no fish.

A. Adaptations


A behavioral adaptation is a change affecting the way an organism naturally acts. This type of adaption could be caused by a change in the surrounding environment or the actions of another species. For example, predatory animals might start hunting in packs -- giving them an evolutionary advantage over solo hunters.

What causes chemical waste ?
Softa [21]

Answer:

  • factories produce toxic chemicals
  • Groundwater Contamination
  • Illegal Dumping
  • Sewerage
  • Leaks and Spills
  • Industrial Growth

Explanation:

Chemical waste is a waste that is made from harmful chemicals (mostly produced by large factories). Chemical waste may fall under regulations such as COSHH in the United Kingdom, or the Clean Water Act and Resource Conservation and Recovery Act in the United States.

[ Impact of Chemical Waste on Water Streams. Improperly managed chemical waste may pollute and contaminate water streams. There are many causes of this type of industrial water pollution, which has both serious and negative impacts on aquatic and human life.]

What do the arrows indicate?
Finger [1]

The best answer would be:

The first option.

Air moves in a direction that creates land breezes.

If you'd like to know more about this, you can read on:

The arrows show how air moves as land breezes are created. In coastal areas, land cools much faster than water, so what happens is the air above it gets cooled down. When this happens, it becomes more dense moves downwards towards land. This causes high pressure and cause winds to blow outwards towards water (ocean).
