The bottom question you asked is A
The correct answers are as follows:
1. Climate determines the type of biome classification that will be made for a particular region.
2. A line could be used to model the quantities of energy at all types of organisms in a food chain.
3. The words "Omnivore, predator, heterotroph" could be used to classify Roseate spoonbills.
4. Plants need bacteria in order to take up and use nitrogen.
5. Carbon is present in all organisms and in the atmosphere.
6. If the shrimp population was depleted by fishing, the copepod population would increase in the ecosystem.
7. If fertilizers from nearby farm fields have entered a lake, the likely change in the ecosystem would be that algae populations will increase, and trout populations will decrease in the future.
To determine the type of biome classification that will be made for a particular region, the most important factor is the climate. Climate includes factors such as temperature, rainfall, humidity, and seasonal changes, which have a significant impact on the plants and animals that can survive in that region.
When considering the amount of energy in a food chain, the shape that could be used to model the quantities of energy at all levels is a pyramid or triangle. This is because as you move up the food chain from producers (plants) to primary consumers (herbivores) to secondary consumers (carnivores) to tertiary consumers (top predators), the energy available decreases. A pyramid or triangle shape represents this decrease in energy.
To classify the Roseate spoonbills species, the words that could be used are omnivore, predator, and heterotroph. These birds consume a variety of food including shrimp, fish, amphibians, and aquatic plants, making them omnivores. They are also predators as they hunt and eat other animals. Finally, they are heterotrophs as they obtain their energy by consuming other organisms rather than producing their own food.
Plants need bacteria in order to take up and use the element nitrogen. Nitrogen is an essential nutrient for plant growth, and certain bacteria have the ability to convert nitrogen gas from the atmosphere into a form that plants can use. This process is called nitrogen fixation, and it involves a symbiotic relationship between certain bacteria and plants.
Carbon is present in all organisms and in the atmosphere, and it plays a crucial role in the cycling of nutrients in ecosystems. Carbon moves through the food chain as consumers consume producers and release carbon dioxide through respiration. Dead organisms are decomposed by decomposers, which release carbon back into the environment. Therefore, carbon is constantly being recycled between organisms and the atmosphere.
If the shrimp population in the given food chain (phytoplankton, shrimp, copepods, sunfish, shark) is depleted by fishing, a likely change in the ecosystem would be an increase in the copepod population. Copepods are primary consumers and feed on phytoplankton. With fewer shrimp to prey on copepods, their population is likely to increase as they have more access to their food source.
If fertilizers from nearby farm fields enter a lake, a likely change in the ecosystem in the future would be an increase in algae populations and a decrease in trout populations. Fertilizers contain nutrients such as nitrogen and phosphorus, which can cause excessive growth of algae in the water, known as algal blooms. These blooms can deplete oxygen levels, making it harder for fish like trout to survive. Consequently, the algae populations increase while trout populations decrease.
