EXPLAIN Make a claim about the affect urbanization has on
biodiversity. Does urbanization always decrease biodiversity? Use
evidence to support your claim and explain your reasoning. Address
the following questions in your answers
• What are the main factors that lead to biodiversity loss in urban
areas?
• How is the size of a habitat related to its biodiversity and its stability?
• Can an ecosystem in an urban area ever return to its previous state?

Answers

Answer:

Urbanization decreases biodiversity. Land development reduces the size of habitats and affects the availability of resources. Larger habitats have a greater potential for biodiversity. If some of the natural habitat is retained, the impact of urbanization may not be as destructive. Assuming human development and its resulting pollution aren’t too extensive, an abandoned urban area could return to its previous ecosystem.

Explanation:

It is found that urbanization affects the biodiversity and the relationship between them is not linear as with the increase in urbanization the area of forest keeps on decreasing which reduces the natural habitat of many species and lead to their extinction.

What affects biodiversity?

Biodiversity of an area is the total number of living organisms (species) living in a particular area. Most of the biodiversity are found in the forests as these are the natural habitats of many animal species.

The ecological studies conducted on the urbanization and biodiversity have found that the urbanization generally shows a negative impact on the biodiversity levels of an area. The relationship between biodiversity and urbanization is not always a linear relation. As the area of urban citied increases, the area of forest decreases which lead to extinction of many important species.

The forests are the natural habitat of animals, as the natural habitat decreases the biodiversity of an area also decreases which affects the stability of the forest.

An ecosystem in an urban area can be returned to a biodiversity-rich area by introducing species and making the habitat more favorable for them.

Answers

Answer:

The answer is a. petroleum

Explanation:

I just took the test and got it right.

The leading cause of global fossil carbon emissions in 2004 was petroleum. Thus, the correct option for this question is A.

What is Carbon emission?

Carbon emission may be defined as the process of liberation of greenhouse gases like carbon dioxide and/or their precursors into the atmosphere over a specified area and period of time. These emissions are significantly contributing to climate change across the world.

When it comes to the global fossil carbon emissions in 2004, the major cause of that was due to petroleum. During that time, people utilize a large amount of petroleum in burning activities. This stimulates the rate of carbon emission in the entire atmosphere which is harmful to the health of living organisms.

Therefore, the leading cause of global fossil carbon emissions in 2004 was petroleum. Thus, the correct option for this question is A.

Without data analysis, valid conclusions about the experiment cannot be made and what the experimenter would have is just raw data that cannot say or answer anything about the experiment.

The data collected from experiments can be analyzed in two ways:

Descriptive data analysis Inferential data analysis

In descriptive data analysis, the collected data is summarized, arranged, or described in such a way that a pattern can be seen at a glance. It includes tables, charts, histograms, etc.

In inferential data analysis, the collected data is treated in such a way that an inference can be arrived at based on the study. This includes testing for a significant difference between means, testing for the goodness of fits, correlations, etc.

Both photosynthesis and cellular respiration are part of the carbon cycle. Which statement best compares these two processes? Both release carbon dioxide as waste. Both provide organisms with usable energy. Both add bacteria to the soil. Both require fixation in order to convert molecules.

Answers

Answer:

Both provide organisms with usable energy.

Explanation:

Both photosynthesis and cellular respiration, a component of the carbon cycle provides an organism with usable energy.

Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water using sunlight to produce energy rich glucose and oxygen gas as a by-product.

During cellular respiration is an oxygen driven aerobic process in which organisms breaks down glucose to produce energy rich ATP.

Both processes furnishes an organism with energy in the end. Although, photosynthesis is an energy building process, cellular respiration breaks down materials to liberate energy. This energy is used by both plants and animals for their living activities.

Therefore, photosynthesis and cellular respiration provides an organism with usable energy.

Ecosystem services Define regulating services in your own words Define providing services in your own words Heroes come in many shapes and forms, but they all do uncommon things in unusual situations. They stand out. We've all heard stories of hero dogs that save their owners. One dog saved his owner by fighting off an alligator. Another woke his sleeping family when a fire broke out in its home. Still others rescue injured or needy people in dangerous situations. One dog even managed to call 911 when his owner suffered a seizure. But one dog, named Ginny, performed heroic acts on a regular basis, not just once or twice in unusual situations. Because of her kindness, many lives were saved.Ginny the dog was adopted by her owner from an animal shelter in 1990. Within days of bringing her home, her owner discovered that Ginny seemed to be able to find cats in distress. On her daily walks, Ginny would often find abandoned, trapped, or endangered kittens or cats that needed rescuing. In one such episode, Ginny found a group of kittens trapped in a pipe. She managed to let her owner know, by scratching and barking at the pipe, that something needed her help. Because of Ginny, all the kittens were saved.Almost daily, Ginny would find cats that needed rescuing or, in some cases, a little love. Ginny's owner reported that when Ginny saw a cat on their walks, she would pull away from her leash and run after the cat. Instead of chasing cats like most dogs, Ginny would nuzzle and lick them, giving them comfort. Because of Ginny, her owner soon found he was caring for hundreds of wild neighborhood cats. In addition, Ginny pushed her owner to adopt more than 20 cats, most of whom had permanent injuries or special needs."When we would go to the pound to drop off donations," her owner said, "Ginny always found the cat that was blind or deaf or hurt in some way. She would sit down in front of the cat's crate and not move until we brought it home."What makes a dog behave in such a kind way? Some believe Ginny had a very strong mothering instinct. But how could she tell when a cat was deaf? How did she know which cats needed love and attention? Regardless of how she did it, Ginny rescued hundreds of cats in her life and set an example we all can follow.Read the following text:On her daily walks, Ginny would often find abandoned, trapped, or endangered kittens or cats that needed rescuing. In one such episode, Ginny found a group of kittens trapped in a pipe.What is the main point of this text? Ginny had a determination unlike other heroic dogs.
