Fungi live by
A. Making their own food.

B. Eating other organisms.

C. Sucking up nutrients made by other organisms.

Answers

Answer:

C

Explanation:

Fungi are heterotrophic.

Fungi are not able to ingest their food like animals do, nor can they manufacture their own food the way plants do. Instead, fungi feed by absorption of nutrients from the environment around them. Most fungi are saprophytes, feeding on dead or decaying material.

Answer:

C. Sucking up nutrients made by other organisms.

Explanation:

Fungi (singular: fungus) are a kingdom of usually multicellular eukaryotic organisms that are heterotrophs (cannot make their own food) and have important roles in nutrient cycling in an ecosystem.

It could be other plants or animals where they get a great place to source their food.

During this time, the fungi kind of hibernates until they get a suitable and beneficial place they can transfer to.

Explain in at least five sentences what you've learned about how
global warming and climate change are impacting our Earth in different regions of the world.

Answers

Explanation: I'd first address the issue as a whole and explain the meaning and the general impacts of climate change, then use a variety of different places. For example, global warming causes the ice caps to melt in Antarctica. Then, explain how this has an impact on the environment meaning that polar bears could be in life-threatening situations and possibly even become extinct in the future which has a further impact on other animals in that food chain and ecosystem. This is just one example. You could also explain the unbearable heat in countries nearer the equator, which prevent crops from growing; the sea levels rising; or extreme weather events like huge flooding or heatwaves. It depends what you have learnt about in class, but I'm assuming it would be about this sort of thing.

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.
