Which is not a benefit of maintaining sustainable forest ecosystems?
Select one:
O a. Empty space on which to build homes
b. Habitat for thousands of species
c. Reduction of erosion in watersheds

Answers

The correct answer as to which is not a benefit of maintaining sustainable forest ecosystems would be empty spaces on which to build homes.

An ecosystem refers to a network of communities interacting together as a unit. A forest ecosystem, therefore, is a community of different plants, animals, and microbes interacting together and with their physical environment as a unit.Sustainable forest ecosystem is a system of managing forest resources in such a way that the ecological processes and functions provided by the forest do not depreciate. The ecological functions of forest ecosystems include the provision of foods, drugs, and raw materials for man, protection of watersheds,  provision of habitats for other species, and playing important roles in the stability of climates.

Hence, not maintaining forest ecosystems in a sustainable way means that some of the functions they perform such as the provision of habitats for species and reduction of erosion in watersheds would be lost.

The only option that is not a benefit of maintaining sustainable forest ecosystems is A.

Classification of Living Organisms

Each organism is different from all others to a lesser or greater extent. Obviously, we and our friends have a lot in common when we compare ourselves with a monkey. But suppose we were to add a cow to the comparison? We would then think that the monkey has a lot more in common with us than with the cow.

Think of all the different forms in which life occurs on earth. On one hand we have microscopic bacteria of a few micrometre in size. While on the other hand we have blue whale and red wood trees of california of approximate sizes of 30 metres and 100 metres repectively. Some pine trees live for thousands of years while insects like mosquitoes die within a few days. Life also ranges from colourless or even transparent worms to brightly coloured birds and flowers.

This bewildering variety of life around us has evolved on the earth over millions of years. However, we do not have more than a tiny fraction of this time to try and understand all these living organisms, so we cannot look at them one by one. Instead, we look for similarities among the organisms, which will allow us to put them into different

classes and then study different classes or groups as a whole.

In order to make relevant groups to study the variety of life forms, we need to decide which characteristics decide more

fundamental differences among organisms. This would create the main broad groups of organisms. Within these groups, smaller subgroups will be decided by less important characteristics.

3. Jakarta: in fact, it is located at a similar altitude of Kuala Lumpur (just in the opposite hemisphere), in the equatorial zone, while Baltimore is located much more north, so in a colder region.

4. Because they are located at approximately same latitude (just in the opposite hemisphere), so they are more or less same distance from the equator, and they receive more or less same amount of sun light, therefore they have similar climate.

Explanation:

How does coral reef damage negatively affect the land? a.) There is more biodiversity. b.) There is a loss of cures. c.) There is more land erosion.

Answers

Answer:

The answer would be C

Coral reef damage negatively affects the land primarily by causing a loss of cures. Hence the correct option is B.

1. Loss of cures: Coral reefs are incredibly diverse ecosystems that provide numerous ecological and economic benefits. One significant impact of coral reef damage is the loss of potential cures and medicinal resources. Many marine organisms, including those found in coral reefs, contain bioactive compounds that have the potential for developing new medicines, treatments, and therapies. By damaging coral reefs, we risk losing these valuable resources and potential cures for various diseases.

2. Biodiversity decline: While option A, "There is more biodiversity," is incorrect in this case, it is important to note that coral reefs are known as the "rainforests of the sea" due to their high biodiversity. Coral reefs support a wide range of marine species, providing habitats, shelter, and food sources. When coral reefs are damaged, either through human activities like pollution, overfishing, or climate change-related factors like coral bleaching, the biodiversity of the reef ecosystem decreases.

3. Land erosion: Option C, "There is more land erosion," is not typically a direct consequence of coral reef damage. However, healthy coral reefs do play a role in protecting the coastline from erosion. Coral reefs act as natural barriers that help dissipate the energy of waves, reducing wave-induced erosion and protecting nearby coastlines from storms and wave action. When coral reefs are damaged or destroyed, the protective function of the reef is lost, potentially leading to increased erosion of the nearby land.

Hence the correct option is B

spores spread into the ant's body and causes behavioral changes in the ant, eventually causing the ant's death.
