Compare and Contrast How are predation,

different?

Answers

Predation, parasitism, and herbivory are similar in that all of them produce harm to the other organism while the other organism benefits. Difference between them is that predation capture and consume their prey, in parasitism, the parasite lodge and lives inside the host while in herbivory, they form adaptations for them to recover.

Herbivory, parasitism, and predation have one thing in common: they all cause harm to the other creature while giving the other organism advantages

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.

Ecosystem ecology refers to how ______ and ________ come into an environment and move around.

Answers

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.

The idea of laissez-faire, or how much the government should do, is

DONE

Answers

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.

Give brainliest pls

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.

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.

Colder climates promote higher biodiversity because they are usually larger in size. This provides space for more organisms.

Answers

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.

Which of the following shows the stage of mitosis in the correct order?​

Answers

answer: B !

hope this helps! please mark me as brainliest :)

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.

So elements can be combined to make a new element but can not be the same element. It’s kinda hard to explain but essentially if it’s the same then it will stay the same and if it’s different then it will stay different. It can’t change in that regard but it can be combined to create anew.
