Species interactions are categorized based on their reciprocal effects (the effects that the interaction has on each species/individual involved).
1. Bees pollinate plants as they move from flower to flower collecting pollen.
This is a mutualistic relationship because the both species involved in this interaction benefit from the interaction. The bee benefits because it obtains nectar which is provided by the plant. The plant benefits because the bee carries the plants pollen to other plants, allowing the plant to reproduce.
2. Green algae grow on the backs of spider crabs living in shallow water.
This is another example of a mutualistic relationship because both species involved in this interaction benefit from the interaction. The spider crab benefits from the camouflage that the algal growth provides, while the algae benefits from the protection from predators provided by the spider crab.
3. Fleas living on skin of dogs and obtaining nutrients from dogs blood.
This is a parasitic relationship because one of the species benefits from the interaction while the other species in negatively impacted by the interaction. The flea benefits from the nutrients obtained from the dogs blood while the dog is negatively impacted by the fleas presence (loss of blood, discomfort).
4. Nitrogen-fixing bacteria obtain nutrients from host plants and use the nitrogen to supply host plants with nitrogen.
This is an example of mutualism because both species in this interaction are benefitting from the interaction. The nitrogen fixing bacteria benefit by receiving nutrients from the host plant while the host plant is benefitting from receiving nitrogen from the bacteria.

Describe the four sources of evidence for evolution upon which Darwin based his ideas in common descent.
Answers
Answer:
- Fossil record
- Geography
- Embryology
- Comparative anatomy
Explanation:
The four types of evidence for evolution upon which Darwin based his ideas were:
1-The geographic distribution of related species. The theory of evolution states that species evolve in geographic areas that were colonized by their ancestors.
2-The fossil record shows successions of organisms through time
3-Embryology: animal embryos in related species are very similar in the early stages of development but differentiate as they grow, thereby suggesting these species evolved from a common ancestor.
4-Comparative anatomy demonstrates physical and structural similarities between species. The species share anatomical similarities because they descend from a common ancestor (i.e., presence of homologies).
Evolution by Darwin was based on the development of the species from the ancestors. The evidence for evolution are fossils, geography, anatomy, and embryology.
What are the pieces of evidence of evolution?The Darwin theory was based on the evolution of the species from their ancestors. The time period has resulted in the change in the features that are based on natural selection.
The evidence for evolution proposed by Darwin is fossil records, comparative anatomy between the species, geographical changes in the species relation, and the embryonic similarities with the evolution.

D.early spring blooming of flowers
Answers
Global warming is mainly caused by an increase in the temperature of atmosphere. The main impact of global warming has the greatest effect on drinking water supplies is melting mountain glaciers.
Which gas is responsible for global warming?The gases that leads to greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor, and fluorinated gases.
These gases increases the temperature of the atmosphere and results in global warming.
This leads to the melting of mountain glaciers which makes a great reduction in the availability of drinking water.
Thus, the correct option is A.

Ecological interactions can be categorized as competition, exploitation, or positive. Describe the types of interactions that fall into these categories, and provide an example of each type of interaction.
Answers
Answer:
Competition is an interaction between organisms or species in which both the organisms or species are harmed. Limited supply of at least one resource used by both can be a factor. This example is if two lions get into a fight and they end up hurting each other.
Exploitation competition occurs when individuals interact indirectly as they compete for common resources, like territory, prey or food. An example of this is when people are farming and they are trying to get the best food available but someone else might have already gotten it.
Commensalism is a positive type of ecological interaction between two species in an ecosystem. In commensalism, the association occurs between members of two different species where one species is benefited the other is neither benefited nor harmed. An example of this is tree frogs who use trees as protection.

Explanation:
Diatoms are single-celled algae that live in houses made of glass. They are the only organism on the planet with cell walls composed of transparent, opaline silica. Cyanobacteria is also called nitrogen fixers because cyanobacteria fixes atmospheric nitrogen in the soil in the available forms of nitrogen to the plants. Whales and jellyfish are nekton because they move in the water independently. Zooplankton feed on phytoplankton for gaining energy and survival.
