Science Ecosystem
Questions to review parts of an ecosystem
| Question | Answer |
|---|---|
| Why does mutualism help two or more animals live? | Mutualism is when two different species help each other out. For instance, in the wild, an animal helps kills a predator that was attacking another animal. The first animal gets nutrients from the predator and the other animal gets protection. |
| What is parasitism and why does it harm all but one organism? | Parasitism is when an organism like a tick or mite chews at and eats another organism. Dogs for example have ticks that suck blood on them. The bad organism gets benefits while the other organism isn't benefiting at all, but yet getting harmed. |
| When a whale has barnacles, it doesn't harm or benefit the whale. It benefits the barnacles by giving a way of transportation to get food. What is this? | This is commensalism. One organism benefits while the other isn't harmed nor benefitted. Commensalism is found everywhere, mainly with insects or ocean animals. |
| When a lion chases a gazelle, the gazelle gives the lion nutrients after the lion captures it's PREY. What is the lion and what is this called? | The lion is a predator and the gazelle is the lions prey. This is pedation, the predator consumes prey, or other consumers. |
| What is symbiosis and how does it effect the population? | Symbiosis is when there are close relationships between two or more species.There are three different species. |
| What is a scavengers job in society? | The scavenger helps get rid of organisms that are dead. They also have a partner that helps them break down called a decomposer. |
| What is a decomposer? Explain what it does as well. | Decomposers are organisms that help our society. They partner with Scavengers to help get rid of animals, plants, and carcasses. Some decomposers are microscopic. |
| How do scavengers and decomposers help us all together? | Scavengers eat most of the dead organism while the decomposers eat microscopic parts. The duo helps get rid of all the dead organisms. |
| In the Galapogos Islands a giant tortoise and a prickly pear cactus help each other. What is this called and how do they help each other? | The Giant Tortoise and The Prickly-Pear Cactus help each in a relationship called Mutualism. The prickly-pear cactus gets new seeds when the tortoise bites off its other part. The tortoise gets nutrients. |
| How does competition effect a ecosystem? | Competition is when animals compete for food and space. This restricts population growth because animals fight to gain these things. |
| What are examples of competition in the wild and even domestic animals? | Fishes inside an aquarium competing for food and space. There are Hyena and Lion competing for territory. An Eagle and a Hawk competing for a prey. |
| Why is there limits to some species of animals? | The fight for food and space mainly. This takes lives of animals each year and restricts population growth. This is a limiting factor. |
| What is a limiting factor? | This basically restricts population growth. Many things such as competition limits population growth. |
| What is carrying capacity? | This is the largest number of one species the ecosystem can support. Limiting factors and carrying capacity play along together. |
| What do limiting factors and carrying capacity have in common? | The more the animals have competition means they have limiting factors. The carrying capacity says how many animals will be standing after all the limiting factors effect the population. |
