7. Your friend jhon is having trouble with his composte bin. the material in his compost bin doesnt seem to be decomposing well. You take a sample of the pile and cehck for the prescenece of microorganisms under the microscope. You see that there are indeed mircoorganisms however they dont appear to be growing very fast. John says he regulary mixes his compost pile to expose it to oxygen but has notice the compsot feels a bit cold. WHat is most likely the explantaion for this probelm?

9. Some students descide to plant their own garden. They want to eat more plant-based diet. For meat, they will buy locally from a butcher. Any remaining plant based scraps will be composted and used to fertilize their garden.
Which part of this plan represents recyling their waste?
A. eating a plant-based diet
B. buying locally
C. composting scraps
D. planting a garden
10. Plants,bison,elk, and wolves are all memebers of an ecosystem. The bison and elk are both primary consumers. While the wolves are predators. over timethe bison completely disapear. Which of the following best describes how the ecosystem may respond to this change, and how it relates to resileiceny and biodiversity?
A. the elk population may increase because they face less competiton for plants, but the inreased elk population may put pressure on plant species. high biodiveristy helps the ecosystem adjust to this change
B. the wolves will immiediatley die off because their food source is gone showing that ecosystems with high biodiveristy are less reilient
C. the plant population will grow uncontrollably because the bison are no longer there to eat them, leading to a loss of balance in the ecos system
D. the disapearence of bison will have no affect because ecosystems with high biodiversity are completely unaffected by changes.

Here are the answers to your questions:
1. **D. birds** - Birds are the most genetically diverse group among the options provided, with over 9,000 species.
2. **A. it breeds rapidly and has no predators in this environment** - This characteristic allows the northern pacific seaster to thrive in new environments.
3. **A. they might introduce other organisms like viruses** - Invasive species can bring new pathogens that affect native species and ecosystems.
4. **B. the coral is susceptible to starvation** - After bleaching, corals lose their symbiotic algae, which provide them with nutrients, making them vulnerable to starvation.
5. **A. coral reef** - Coral reefs are known to be the most diverse ecosystems in the world.
6. **A. tourism** - The fossilized stumps could attract visitors and generate tourism revenue.
7. **B. the compost pile contained incorrect amounts of greens and browns** - The balance of green (nitrogen-rich) and brown (carbon-rich) materials is crucial for effective decomposition.
8. **D. nitrogen** - Green materials typically have high nitrogen content.
9. **C. composting scraps** - Composting scraps is the part of the plan that represents recycling their waste.
