Step-by-step solution for: Competing for Resources | 3rd Grade Reading Comprehension Worksheet
It looks like you've uploaded a worksheet titled "Competing for Resources" from a science curriculum (likely for middle school or early high school), focusing on ecology and population dynamics. The worksheet is based on a reading passage about how organisms compete for limited resources such as food, water, and shelter.
Since I can't view images directly, I’ll solve the questions based on the text you provided in your message. Here’s the full analysis of the worksheet:
---
- All living things need resources to survive: food, water, shelter, and space.
- These resources are limited, so organisms must compete for them.
- Competition occurs when there isn’t enough of a resource for everyone.
- When one organism gets more resources, others may suffer.
- Organisms adapt to their environment to get better access to resources.
- Over time, populations grow until they reach the carrying capacity of the environment — the maximum number of individuals that can be supported.
- If populations grow too large, resources become scarce, leading to starvation, migration, or death.
- Predation (e.g., hunting) helps regulate populations by keeping numbers in check.

#### 1) Why do organisms sometimes have to compete for resources?
Answer:
Organisms have to compete for resources because resources like food, water, shelter, and space are limited, but there are often many organisms needing them. Since there isn’t enough for everyone, organisms must compete to survive.
Explanation:
This is a fundamental concept in ecology. Limited resources mean not every organism can get what it needs. For example, if there’s only one water source in a dry area, animals will fight or wait to use it — this is competition.
---
#### 2) What kinds of things are beneficial for organisms?
Answer:
Things that are beneficial for organisms include food, water, shelter, and space.
Explanation:
These are essential for survival and reproduction. Food provides energy, water is necessary for all life processes, shelter protects from predators and harsh weather, and space allows room to live and reproduce.
---
#### 3) What kinds of things are detrimental for organisms?
Answer:
Things that are detrimental include lack of food, water, or shelter, overcrowding, predation, and disease.
Explanation:
When resources are scarce, organisms may starve or die. Overcrowding leads to increased competition and stress. Predation removes individuals from a population. Diseases can spread quickly in dense populations.
---
#### 4) What happens when populations grow too large for an area?
Answer:
When populations grow too large, resources become scarce, which leads to starvation, disease, migration, or death. Eventually, the population size decreases until it matches the carrying capacity of the environment.
Explanation:
The carrying capacity is the maximum number of individuals an environment can support. Once that limit is reached, the population cannot grow further. Nature "corrects" this through natural checks like starvation or migration.
---
#### 5) Do you think hunting or relocation is a better solution for overcrowded animal populations? Why?
Answer (Sample):
Hunting can be a better solution than relocation because it controls population size naturally and prevents overuse of resources. Relocation might cause problems in new areas (like spreading disease or disrupting other ecosystems). However, both methods have pros and cons, and the best choice depends on the species and situation.
Explanation:
This is an open-ended question asking for opinion with reasoning. Hunting (like regulated game hunting) mimics natural predation and keeps populations balanced. Relocation can help some animals but risks introducing invasive species or stressing animals. Many conservationists prefer non-lethal methods when possible, but population control is necessary to maintain ecological balance.
---
- This worksheet teaches students about ecological balance, competition, and population regulation.
- It emphasizes that natural systems self-regulate, but human intervention (like hunting or relocation) may be needed.
- Encourages critical thinking — especially in Question 5.
