Answer: Net primary productivity is the amount of gross primary productivity remaining after respiration, which is about 40 and 85 percent. Sloughs and marshes, as well as tropical rain forests, possess the highest rates of net primary productivity; deserts have the lowest.
Explanation:
I explained on the top-
The highest rate of primary productivity in terrestrial environments takes place in swamps and marshes and in tropical rainforests, and in aquatic environments it takes place in algal beds, estuaries, and reefs.
• In ecology, primary productivity refers to the rate at which conversion of energy to organic substances takes place by the photosynthetic producers that attain energy and nutrients from the sunlight, and chemosynthetic producers that attain chemical energy via oxidation.
• The majority of the energy assimilated by plants via the process of photosynthesis is not stored as organic substance, however, is utilized at the time of cellular respiration.
• In the process, the organic components like proteins, carbs, and fats are dissociated to provide energy in the form of ATP for the metabolic needs of the cells.
• The energy not utilized is stored in the tissues of the plants for future use and is known as the net primary productivity.
• The highest net primary productivity in terrestrial environments takes place in marshes and swamps and in tropical rainforests, and in aquatic environments it takes place algal beds, estuaries, and reefs.
These environments are mainly critical for the sustenance of global biological productivity.

Explanation:
Ecosystem ecology refers to how ______ and ________ come into an environment and move around.
1. biotic
2.Natural environment
Ecosystem ecology refers to how energy and nutrients come into an environment and move around.
What is ecosystem?Ecosystem ecology is concerned with the interactions and movements of energy and nutrients within an ecosystem, which are critical for understanding how ecosystems work.
Photosynthesis by primary producers, such as plants, introduces energy into ecosystems, which then flows through the food chain to consumers.
Nutrients such as carbon, nitrogen, and phosphorus cycle through the ecosystem via biological and geological processes and are critical for the ecosystem's health and productivity.
Understanding how energy and nutrients enter, move, and cycle within ecosystems is therefore critical for understanding ecosystem functioning and sustainability.
Thus, the movement of energy and nutrients in an ecosystem is referred to as ecosystem ecology.

How are predation, parasitism, and herbivory similar?Herbivory, parasitism, and predation have one thing in common: they all cause harm to the other creature while giving the other organism advantages. The difference between them is that predators capture and eat their prey, but parasites lodge inside their hosts and dwell there, while in herbivores, adaptations are made to help the prey survive.

Which of the following shows the stage of mitosis in the correct order?
Prophase, prometaphase, metaphase, anaphase, telophase, cytokinesis is the correct order of mitosis. Therefore, option (B) is correct.
Mitosis is a cellular process that ensures the accurate division of a cell's genetic material into two identical daughter cells. It consists of several distinct phases that occur in a specific order.
Interphase: The cell prepares for division by growing, duplicating its DNA, and synthesizing necessary proteins.
Prophase: Chromatin condenses into visible chromosomes, the nuclear membrane disintegrates, and spindle fibers form.
Metaphase: Chromosomes align at the center of the cell, known as the metaphase plate, and attach to spindle fibers at their centromeres.
Anaphase: Sister chromatids separate and are pulled to opposite ends of the cell by the spindle fibers.
Telophase: Chromosomes reach the opposite poles of the cell, and new nuclear membranes form around them. The chromosomes begin to decondense.
Cytokinesis: The cytoplasm divides, leading to the formation of two distinct daughter cells, each containing a complete set of chromosomes.

An oak tree falls in a forest. It kills some ants and stops grass from growing
below it. What type of disturbance is this?
O A. Secondary
O B. Primary
O C. Cyclical
O D. Small
Answer:
This is O D. Small type of disturbance.
Explanation:
Small-scale biological disturbance.
Answer:
O D. small
Explanation:
In ecology a disturbance is an event that causes a change in the environment. There are small-scale disturbances and high-magnitude disturbances. Small-scale disturbances are typically driven by biological processes -for example the fall of a tree- while high magnitude disturbances are typically driven by physical processes -for example, storms-. Small-scale disturbances as single-tree blowdowns are very important to create and maintain diversity and heterogeneity in the forest.

The idea of laissez-faire, or how much the government should do, is
DONE
Answer:
Laissez-faire means that the government does not interfere with people's right to pursue happiness.
The idea of laissez-faire, or how much the government should do, is debated heavily.
Explanation:
Laissez-faire is the main concept defended by economic liberalism and capitalism, mainly in the USA and other countries that adopt this type of concept. In a simple way, Laissez-faire can be defined as the separation of the State and the commerce of a region. This means, that in places where Laissez-faire is adopted, the State, ie the government, does not have the right to interfere in any type of commercial relationship and should only be responsible for guaranteeing property rights and consumer protection, otherwise, trade must regulate itself, within its own limits.
While many people see this policy as beneficial, preventing government from interfering with people's happiness, others believe that Laissez-faire is not beneficial and that government interference, or lack of it, should be discussed.

Colder climates promote higher biodiversity because they are usually larger in size. This provides space for more organisms.
Answer:
False
Explanation:
The relationship between climate and biodiversity can be defined as follow: warmer climates are generally associated with higher biodiversity because these conditions promote the life of primary producers such as those organisms that produce organic compounds using simple substances and energy from light. Primary producers form the basis of the food chain, thereby their presence is fundamental to generate sustainable high biodiversity environments. For example, warmer climates such as tropical ecosystems promote plants (i.e., primary producers) to grow year-round, thereby supporting more organisms (i.e., species richness) that rely on plants.

Because of their capacity for rapid growth and reproduction, or because their new environments are devoid of any native predators or pests, invasive species frequently thrive in their new ecosystems. Thus, option B is correct.
What is a characteristic of invasive species?An invasive species doesn't develop slowly; on the contrary, they accelerate their growth because they are superior to all other species and have taken over the area completely.
Because of this, invading species may pose a threat to native species and interfere with crucial ecosystem processes.
A species must be easily adaptable for it to be invasive. It needs to multiply swiftly. It must result in harm to local property, the local economy, or the local fauna and flora. Accidental introduction of invasive species into a new area is common.
They are so successful because they can adapt and aren't intrusive. Because they have no competition, they are thriving while not being threatened.
Therefore, They take resources from native species.
