Answer:
Approximately 2000 species become extinct on earth each day.
Explanation:
The extinction is defined by no presence of a particular species on anywhere on the earth. It is estimated that there are 150-200 species present in environment gets extinct every day. The every day extinction of species is in the range of 200 to 2000. The high extinction rate can cause severe negative impact on the environment. The process of extinction can cause ecological imbalance.
b. Plants perform photosynthesis
c. Plants perform cellular respiration
d. Plants perform both of photosynthesis and cellular respiration
Plants perform both photosynthesis and cellular respiration.
During photosynthesis, the plant converts solar energy into chemical form. Plant captures light that comes directly from the sun and through different ranges of reaction, using its energy to build sugar molecules known as glucose.
Glucose consists of six oxygen atoms, six carbon atoms and twelve hydrogen atoms. When plant produces glucose molecules, it gets the carbon and oxygen it required to make the glucose molecules from carbon dioxide taken from the air.
Although there is no presence of hydrogen in carbon dioxide, therefore the plant uses water to replace hydrogen. The world is surrounded with large volume of water and every water molecules is made of two hydrogen and one oxygen atom.
For the plant to take the hydrogen needed to build molecules, it use the energy obtain from the sun to split the water molecule apart. During photosynthesis, plant consumes carbon dioxide water, and produces oxygen and glucose.
The glucose produced by the plant is important for cellular respiration. During cellular respiration, the presence of chemical energy in the glucose molecules is converted into a form that plant can utilize for reproduction and growth.
The first step of respiration is known as glycolysis, at this step the glucose molecule is broken down into molecules that are smaller also known as pyruvate and a little energy is also released in the form of ATP. The result of cellular respiration in plant is that it consumes oxygen and glucose and produces water, carbon dioxide and ATP energy molecules

KEYWORDS:
The statement that plants perform both photosynthesis and cellular respiration is correct. Photosynthesis is a process used to synthesize food with sunlight and cellular respiration coverts the produced sugar into usable energy.
The correct answer to the question is d. Plants perform both photosynthesis and cellular respiration.Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigments. Oxygen is a product in this process, not a reactant.Cellular respiration is the process by which cells in plants, animals and other organisms break down sugar and turn it into energy, which is then used to perform work at the cellular level. This process does use oxygen as a reactant to convert the stored sugar into usable energy.
Therefore, plants do both photosynthesis (to make sugar and produce oxygen) and cellular respiration (to break down the sugar into usable energy).

2)mass wasting
3)a glacier
4)a mudflow
Answer:
It is Glacier, I just did my assignment and got it correct.
Explanation:
Deforestation, pollution and loss of natural resources all are possible due to human involvement in devastating the environment i.e. urban sprawl. Thus, correct answer is option D.
Further Explanation:
Urban sprawl is another word used for urbanization. This refers to the migration of the population from the populated towns as well as cities to the reduced density of residential development. This shift generally leads to reduction of natural resources and supplies. The final result is the spreading of a city over more and more rural land. This refers to the expansion of poorly planned and low-density development. This spreads over large amounts of land and puts long distances between storage home and work, and thus, creates high segregation between commercial and residential uses having harmful impacts on the individuals living in such regions. The wildlife and ecosystems are displaced.
Some argue that this has its benefits like making local economic growth. However, it has many uninvited consequences for the environment as well as residents like higher water and air pollution, elevated jams and fatalities in traffic, and loss of agricultural capacity. There is also an increased car dependency.
