Textbook Question
Chapter 20, Problem 15PS
Imagine that you have been chosen as the biologist for the design team implementing a self-contained space station to be assembled in orbit. It will be stocked with the organisms you choose, creating an ecosystem that will support you and five other people for two years. Describe the main functions you expect the organisms to perform. List the types of organisms you would select, and explain why you chose them.

ANSWER THE FOLLOWING:
If you are to engage into aquaculture, how will you do it considering your current location and available resources. What species, level of management and culture system will you consider? (imagine your location is Philippines)
On the otherhand, if all resources are available and favorable, what brackishwater and marine species will you grow/culture? Discuss your criteria of considering these species. Describe the level of management and culture system that you will employ.
An ecosystem is made up of plants, animals and microbes on one hand and air, water and mineral soil on the other hand. Discuss how these factors are connected to form the ecosystem.
Climate change causes problems for organisms that have adapted
to their environments. Please list two problems that climate change
could cause which would prevent organisms from surviving in an
environment to which they are well adapted.

- Scenario: You have been hired by an electric utility company whose stockholders are really pressing the company on ESG matters (environmental, social, governance). The company owns thousands of acres of land surrounding one of its powerplants and leases much of this land to local farmers for agriculture. However, local environmental groups have been stating concerns in the local newspaper about the loss of insect biodiversity on in meadows surrounding the agricultural activities. You have been tasked by the company to develop an experiment to investigate whether a loss of insect biodiversity is occurring in these meadows because of these agricultural activities. Action Steps: Propose a coherent and testable hypothesis that captures some aspect of this concern. Identify the independent and dependent variables in this experiment. Identify any possible confounding variables that might influence your experiment. Identify appropriate controls for your experiment.

This, in turn, stimulates the formation of possible explanations, termed hypotheses, that can be tested by collecting data from a study or an experiment. Advocates for organic farming claim that their methods result in a number of benefits to farmers, consumers, and the environment. A group of scientists is conducting a study on the benefits of organic farming. What should be the final product of the observational stage of their study?arrow_forward
- A factory located near a river pumps heated water into the river. The heated water decreases the amount of oxygen in the river. An STS class is discussing what this decrease in oxygen would do to the river. Bam thinks less oxygen would change the type of organisms that live in the river. Mel thinks the type of organisms would stay the same, but there would be a lot less organisms. QUESTIONS: Who do you agree with? Bam?Mel? both Bam and Mel? Why are they right? What would happen if oxygen in a stream decreases?arrow_forwardAn organism is able to live well in its environment because of special characteristics called * a) Abiotic factors B) Biotic factors C)Aggregates D)Adaptationsarrow_forwardReference book: https://drive.google.com/file/d/1b7JbGY8r59rexIo0UK_MBv7luxpdLAvB/view?usp=sharing This subject is about people and ecosystem.

Bees pollinate plants as they move from flower to flower gathering nectar. 2. Green algae grow on the backs of spider crabs living in shallow water, camouflaging the spider crabs while the crabs protect the algae from predators. 3. Fleas live on the skin of dogs and obtain nutrients from the dogs' blood. 4. Nitrogen-fixing bacteria obtain nutrients from their host plants and use the nutrients to supply nitrogen to the plants. Which statements best describe these relationships? O Relationships 1 and 4 are examples of mutualism. Relationship 2 is an example of con sm.

- Give typing answer with explanation and conclusion Which of these is not one of the benefits of organic agriculture? Group of answer choices Organic food contains more vitamins and minerals Organic farming uses less fossil fuels Organically raised animals are given no antibiotics Organic agriculture enhances biodiversityarrow_forwardYou have two identical bags and fill them with the same amount and type of leaves. You put the identical bags in two different areas of a river. After several weeks, one set of leaves has almost disappeared and the bag is full of organisms. The other set of leaves is still mostly whole and the bag has few organisms in it. Questions: What are some ways the two different areas of the river could be different? How might these differences explain why the leaf packs in one area have more organisms than the leaf packs in another area?arrow_forwardVisit a specific area in your school or at home (e. g. garden). Using a pen and a clean sheet of paper, list down five (5) organisms found in that area and describe the value of each organism. Then, classify the value of the organisms by putting a check mark (/) on the space under the correct column. An example has been given. If you think that an organism has more than one value, put a check mark (/) on each.arrow_forward
