Answer:
1. oceanic-oceanic boundaries
2. oceanic-continental boundaries
3. continental-continental boundaries
Explanation:
The three types of plate convergence are:
1. oceanic-oceanic boundaries: this occurs when two oceanic plates clash; thereby the heavier plate forms below the lighter plate resulting in dark, heavy, basaltic volcanic islands.
2. oceanic-continental boundaries: this occurs when there is a collision between oceanic and continental plates, resulting in the downward movement of oceanic plate, while the volcanic arc rises on land
3. continental-continental boundaries: this occurs due to the massive crust of slabs clashing against each other. Thereby leading to big mountains forming from folded, faulted, and thickened convergent boundaries
 
        
             
        
        
        
Answer: Convergent boundaries or subduction zones are where two plates collide into each other. These are the most common type of tectonic plate along the Pacific Ring of Fire. But continents don’t always collide with oceans. Sometimes, continents collide with other continents, which is part of the formation of mountains.

Explanation:
Ecosystems exist at a range of scales and involve the interaction between biotic and abiotic components. An example of a small scale UK ecosystem to illustrate the concept of interrelationships within a natural system, an understanding of producers, consumers, decomposers, food chain, food web and nutrient cycling.
