This is a type of suckerfish that will attach itself to sharks and other big fish to catch an underwater ride.

What are 5 examples of competition?

Types of Competition and Examples

Plants compete with each other for light exposure, temperature, humidity, pollinators, soil nutrients and growing space. Microbes compete for chemical substrates. Animals fight over territory, water, food, shelter and prospective mates.

What are the 2 types of competition?

There are two different types of competition:

  • Intraspecific competition occurs between members of the same species. For example, two male birds of the same species might compete for mates in the same area. ...
  • Interspecific competition occurs between members of different species.

Is competition a -/- interaction?

Competition is a biological interaction between two or more organisms of the same or different species where the species compete with each other for different resources. Most of the competitive interaction occurs for the need of food sources that occur in a limited supply when compared to demand.

What is an example of resource partitioning?

One way that species can partition resources is by living in different areas of a habitat versus their competitors. One common example is the distribution of lizards in the Caribbean islands. The lizards mostly eat the same types of food—insects.

What are the 3 types of resource partitioning?

Key Terms

  • Resource partitioning: when species divide a niche to avoid competition for resources.
  • Interspecific competition: competition between species.
  • Intraspecific competition: competition between individuals of the same species.

What is temporal resource partitioning?

Temporal resource partitioning is when two different species split up when they hunt for food. What is spatial resource partitioning? When two organisms such as plants get their food from different areas of the habitat.

Can plants be keystone species?

Keystone species can also be plants. Mangrove trees, for instance, serve a keystone role in many coastlines by firming up shorelines and reducing erosion. They also provide a safe haven and feeding area for small fish among their roots, which reach down through the shallow water.

Is kelp a keystone species?

A Healthy Kelp Forest Is Finely Balanced

Sea otters are a keystone species, because they play an extremely important role in maintaining the structure of the ecological community. Without them the type and abundance of species in the community would be totally different.

Is a mosquito a keystone species?

Mosquitoes are not a keystone species. This is because there is no ecosystem in which they play such a vital role that the health of the ecosystem...

Are humans keystone species?

Humans do qualify as a keystone species, particularly in urban ecosystems. A keystone species is a species that has a disproportionate effect on its environment relative to its abundance. Such an organism plays a role in its ecosystem that is analogous to the role of a keystone in an arch.

What if humans went extinct?

What would happen if humans suddenly went extinct? Lacking human oversight, glitches in oil refineries and nuclear plants would go unchecked, likely resulting in massive fires, nuclear explosions and devastating nuclear fallout. “There's going to be a gush of radiation if suddenly we disappear.

What species would become dominant if humans died out?

They have colonised the entire planet, from the stratosphere to the deepest ocean, and despite all our technology, antibiotic-resistant bacteria continue to kill hundreds of thousands of us every year. When humans are gone, other species may take our place, but bacteria will continue to dominate the planet.

Are Wolves keystone species?

Wolves are what's referred to as a “keystone species”, which is any species that other plants and animals within an ecosystem largely depend on. If a keystone species is removed, the ecosystem would drastically change, and in some cases, collapse.

What would happen if the gray wolf went extinct?

If wolves went extinct, the food chain would crumble. The elk and deer population would increase (see chart on next slide) and eat the cow and other livestock's food. Then we, the Humans, would have a food shortage in beef and dairy and possibly shortages in other food products too.

Why is a GREY wolf a keystone species?

Wolves are a critical keystone species in a healthy ecosystem. By regulating prey populations, wolves enable many other species of plants and animals to flourish. In this regard, wolves initiate a domino effect – “touching” songbirds, beaver, fish, and butterflies.

Why were GREY wolves removed from Yellowstone?

Much of the wolves' prey base was destroyed as agriculture flourished. With the prey base removed, wolves began to prey on domestic stock, which resulted in humans eliminating wolves from most of their historical range. Predator control, including poisoning, was practiced in the park in the late 1800s and early 1900s.
