Answers

Answer 1
Answer:

The animal burrows in Diagram B are an example of mechanicalweathering, and weathering is of many types, such as physical, chemical, and mechanicalweathering.

What are the different types of weathering?

Weathering is a process in which the chemical composition of the matter may or may not change, the size of the matter may or may not change, etc. There are different types of weathering, such as physical weathering, chemical weathering, and mechanical weathering.

Mechanical weathering is a type of weathering in which changes can be seen, such as roots growing in rocks, whereas chemical weathering changes the chemical composition. The chemical weathering changes the composition so that the original and the new composition change in seen in the case of the rocks, the soil, etc., and in the physical weathering the size changes, such as from the large rock to the smaller form.

Hence, the animal burrows in Diagram B are an example of mechanicalweathering.

Which of the following is not part of the nitrogen cycle? a conversion of atmospheric nitrogen into usable organic compounds by bacteria b breathing in nitrogen gas from the atmosphere c nitrogen fixation d conversion of nitrogen from decaying organisms into ammonia

Answers

The following is not part of the nitrogen cycle - bbreathing in nitrogen gas from the atmosphere.

The nitrogen cycle is one of the biogeochemical cycles which includes the conversion of nitrogen into multiple chemical forms as it transfers among the atmosphere, terrestrial, and marine ecosystems.

  • carried out through both biological and physical processes
  • Nitrogen is the major part of the air we breathe, but it is unreactive, therefore, not participate in respiration at all so, nitrogen breathe out again.
  • Nitrogen fixation: conversion of atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation, mainly fixed by bacteria.
  • Ammonification: The nitrogen present in the tissues of a dead organism is in the form of organic nitrogen, which decomposes the tissue and releases inorganic nitrogen back into the ecosystem.

Thus, The following is not part of the nitrogen cycle - bbreathing in nitrogen gas from the atmosphere.

The Michigan forests contain a variety of tree species. What happens to the tree population when a forest losses its diversity; when only one tree species dominates an area? Students in biology class conducted the following simulations to predict the effects oon one tree species due to the presence of an invasive insect species: the hemlock woolly adelgid. Simulation #1 - 1. 28 students were given a card marked with H for hemlock 2. Each student moves around the room to meet three other students and write their names on their card. 3. The teacher represents the hemlock woolly adelgid.. He touches one student who dies and sits down. That student reads the names on his/her card. 4. Each student named, also dies and also reads the names on their cards. 5. Continue to all the students sitting have read the names on their cards. Count the number of students still standing. Simulation #2 1. Students are given cards marked H - hemlock; JP - jack pine; F - balsam fir; A - aspen; B - birch. 2. Repeat steps #2 - #5 from Simulation #1. 3. This time ONLY the students marked H will sit down. The other species of trees do not die. Based on the students' simulations, what conclusion can be drawn?A)Biodiversity halts the impact of disease and/or insect damage in an ecosystem.
B)Planting hemlocks in stands by themselves will save the other tree species growing throughout Michigan.
C)By planting a variety of tree species, you reduce the impact of specific insect damage on a forest ecosystem.

Which of the following populations would be least likely to survive a change in its ecosystem? A. brown bears that can eat a variety of different kinds of food B. koalas that eat only eucalyptus leaves C. grasses that can grow in normal or contaminated soil D. bacteria that can grow in both hot and cold environments

Answers

koalas that eat only eucalyptus leaves C. would least likely survive in a change of ecosystem.

What are the Kaolas?

The koala or koala bear refer to arboreal herbivorous marsupial that are majorly found in Australia. It is the only remaining representative of the family Phascolarctidae and its closest living relatives are the wombats.

They survive in most climate.

Therefore, koalas that eat only eucalyptus leaves C. would least likely survive in a change of ecosystem.
