Two of the flamingos in the video are pecking each other, fighting for food. This is an example of intraspecific competition, or competition between two members of the same species. Use this information to fill in the blank and complete the sentence. Not all answer choices will be used.

The flamingos are likely competing for food because there is
amount available.

Like all organisms, flamingos rely on a variety of resources to survive. Some examples of resources are listed below. Classify each resource as biotic (living) or abiotic (nonliving).

Imagine that after one year, this group increases from 50 flamingos to 100 flamingos. After two years, do you think the population will double again? Why or why not?

Answer 1

1. Based on what you see in the video, the most likely food source for flamingos is:

C. Tiny shrimp and algae

Flamingos primarily feed on small crustaceans, such as shrimp, and various types of algae, which give them their characteristic pink color.

2. The flamingos are likely competing for food because there is limited amount available.

Intraspecific competition occurs when individuals of the same species compete for the same resource, which indicates that the food supply may not be sufficient for all individuals present.

3. Classifying the resources:

Biotic Resources:

• Tiny shrimp
• Algae

Abiotic Resources:

• Water
• Sunlight
• Soil

(Note: The specific abiotic and biotic resources depend on your answer bank; I provided standard examples based on flamingo habitats and needs.)

4. After two years, it is unlikely that the population of flamingos will double again to 200. This is due to factors such as limited resources (food and habitat), increased competition, predation, disease, and environmental constraints that can inhibit population growth as it becomes larger. Population growth often follows a logistic model rather than a simple exponential model as resources become limiting.
