honeycreepers are hawaiian birds.they share the same habitat differently but have adapted to the habitat differently. each one has diffrent shaped beak which allows them to eat different foods.what conclusion can you make about the relationship between ninche and competition

Answers

Answer:

Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.

Explanation:

THIS BASICLY MEANS THAT IF 2 SPECIES HAVE NICHES THAT OVERLAP THEY WILL NATURALY COMPETE FOR THE SAME RESOUCES THE SPECIES WITH THE BETTER ABILITY TO HUNT WILL WIN

The relationship between niche and competition can be observed in the example of honey creepers, which are Hawaiian birds that share the same habitat but have adapted to it differently.

What is competition?

Competition affects the size of the realized niche, which is a factor in how many species are present in a community. In biology, competition refers to an interaction between organisms or species when both need a resource that is in short supply, such as food, water, or a particular area.

Because each honey creeper's beak is unique and can eat a variety of foods, there is less competition for resources, and they can coexist in the same habitat. This is an illustration of niche differentiation, a strategy used by competing species to lessen rivalry by using various methods to exploit their environment.

As a result, the significance of the relationship between niche and competition are the aforementioned.

Please may I have help with this question.
Thank you

Answers

Answer:

The economic effects were more significant than the social effects.

Explanation:

The social effects included the flooding of over 600 houses and the evacuation of 16 farms. Villages, such as Borrowbridge,  were cut off, and power supplies, roads, and railways were also affected. The Bristol to Taunton line was closed at Bridgwater for instance. The environmental impacts were even worse though; an enormous volume of debris dumped by the floodwaters had to be cleaned up and stagnant waters had to be re-oxygenated before being pumped back into rivers. However, I think the worse impact of all was the contamination of all flooded areas by oil, agricultural chemicals, livestock effluent, and human sewage. I think that this is the worst impact because of its potential for causing harm to humans and other animals.

In conclusion, I think that the socio-economic and environmental effects of this flood were both important but that the environmental effect was more important, because of the potential to cause harm.

2. Why did Cuba turn to organic farming? What could their approach teach us about how other countries could be compelled to farm organically?


3. How do you think more open relations with the U.S. will affect Cuban farming practices?

Answers

1. Cuba's gross domestic product shrunk 35%, imports and exports both fell over 80%, and many domestic industries shrank considerably.

2. Cuban citizens started to grow crops on their balconies whilst farmers, left with no petrol or pesticides, were forced to resort to traditional methods to feed themselves. Cubas approach could teach us a greater focus on domestic production of domestically consumed produce, and a dramatic reduction of petroleum products in all aspects of food production.

3. U.S imports will take away the authentic practices of the Cuban farming ways.
